Imagine for a moment: it's 1962, and the PTT has just made a decision that will mark the history of France for decades to come. Suddenly, all those little gray and green 2CVs that have been crisscrossing our countryside for the past ten years will have to change color. Off to the workshop for a complete makeover: they all come out as yellow as canaries .

And every time I see one of these little yellow 2CVs in the street, I tell myself that there is something magical about this color. Because behind this very special yellow, there is an incredible story that goes back to the Austro-Hungarian Empire, through two world wars, and takes us to the rounds of our postmen today.

But before diving into this adventure, let me tell you something: this story begins with disobedience . Without an engineer who refused to obey orders, the 2CV might never have existed. And without the 2CV, well, our postmen would have had much more complicated rounds in the 50s.

The secret origins of a yellow that spans the centuries

To understand why our mail carriers drive yellow vehicles, we have to go back a long, long way. I'll take you back to 1490, when the Tassis family—later to become Thurn und Taxis—organized the postal service for the Empire. And guess what colors they chose? Black and yellow, the colors of imperial power.

It's crazy when you think about it: our modern-day mail carriers are inheriting a tradition that's over 500 years old! Over time, black fades, but yellow remains. It lives on through the centuries like a little sun that refuses to go out.

Well, you're going to say to me, "This Empire story is all very well, but what do we do in France?" Well, that's precisely why France is going to take a long time to adopt this color. A very long time, in fact .

The French Revolution of May 15, 1962

For decades, French PTT vehicles were a bit of a festival of dull colors. Gray here, wagon green there, and even dark blue for the mailboxes. The problem? In bad weather, you couldn't see anything at all . Postmen would get hit, mailboxes would go unnoticed, it was a real safety concern.

So on May 15, 1962, bang! Official decision: all French postal vehicles go yellow. But not just any yellow, mind you. The "AC311" yellow, specially created by Citroën . A striking yellow, visible from afar, that protects our mail carriers.

And there, I tell myself that this is exactly what fascinates me about vintage cars: these details that tell the story of an entire era. This color is not there by chance, it has a mission, a story, a soul.

Pierre-Jules Boulanger: the man who revolutionized rural France

But let's get back to the story of the 2CV, because without it, our postmen might still be on their bikes! And this story has a hero: Pierre-Jules Boulanger . Born on March 18, 1885, this guy was anything but ordinary.

Imagine: an airplane pilot during the First World War—at a time when flying still meant risking your life with every takeoff—then CEO of Citroën in 1937. And above all, an absolute visionary. His obsession? To create a car that everyone could afford, even the most modest farmer in our countryside.

I swear, when I read the specifications he gave to his engineers, it makes me smile: "I want a car that can carry two farmers in clogs, 50 kg of potatoes or a barrel, at a maximum of 60 km/h, consuming 3 liters per 100 km." And the killer detail: "It must be able to drive in a plowed field with a basket of eggs without breaking a single one."

André Citroën, the misunderstood genius

But before Boulanger, there had already been a visionary at Citroën: André-Gustave Citroën himself. A graduate of the École Polytechnique and a brilliant engineer, this man had revolutionized the French automobile industry in 1919. By the early 1930s, Citroën was the fourth largest automaker in the world ! Not bad for a French brand, right?

André Citroën was a bit like the Elon Musk of his time: revolutionary ideas, crazy PR stunts - he even had his name installed in illuminated letters on the Eiffel Tower! But as is often the case with geniuses, he died too soon in 1935 to see the birth of the 2CV.

1952: The rural touring revolution

And then came 1952. The year everything changed for our postmen . Until then, since 1830, the 5,000 rural French postmen had been making their rounds on foot or by bicycle. Can you imagine? In all weathers, on all roads, with the mail on their backs.

This is where the 2CV AZU van arrives. The small revolution on four wheels that will change life in our countryside. No more cycling tours in the rain, no more mail bags that weigh a ton . Now, the postman has his little mobile office, his protection against the weather, and above all, he can carry much more mail.

I think this democratization is beautiful. The 2CV wasn't just a car, it was a tool for social progress. It allowed our rural residents to stay connected, to receive their letters more quickly, and not to be forgotten by modernity.

Besides, I have a passion for cars from this era—from 1950 to 1999—because they all tell stories like this one. Stories of ordinary people who changed the daily lives of millions of French people. This is exactly what I share on my website bernardminiatures.fr: these 1/43 scale miniatures that capture the soul of these vintage vehicles.

I'm not a big site, so I often only have one or two pieces of each model in stock, but that's also what makes it charming. I have 2CVs of course, but also Renault 4Ls, Citroën HYs, Peugeot 403s... pretty much all the vehicles that marked this era. Delivery is free from 75€ in France, and I take care to package well because these little wonders deserve respect.

Go take a look at bernardminiatures.fr if you're interested, you'll see that I have some gems that are really worth the detour.

Now, let's get back to our postal 2CVs, because their story is getting even more interesting.

The Mystery of the Reverse Lever

So here's an anecdote that has puzzled me for years. The PTT 2CVs had a special little lever that allowed you to lock the reverse gear . You hear me right: our postmen could no longer reverse without unlocking this mechanism!

But the crazy thing is, no one really knows why. The archives are silent on the subject. Was it to prevent mail carriers from turning around too easily? To prevent theft? For insurance reasons? The mystery remains .

I have a theory: maybe the administration wanted to make sure its mail carriers finished their rounds instead of turning around at the first obstacle. But hey, that's just my guess.

The heroic disobedience of Henri Loridont

But wait, because the craziest story is the one that almost deprived us of 2CVs forever. It's 1940, the Germans arrive . Pierre-Jules Boulanger, in a patriotic surge, orders the destruction of all 2CV prototypes. Around 250 examples that represent years of research and development.

The idea? Prevent the Germans from getting their hands on these French innovations. Except that one engineer, Henri Loridont, refuses to obey . He secretly dismantles a prototype, puts it in crates, and hides it.

I swear, without this disobedience, there might never have been a 2CV! No Deudeuche, no popular automobile revolution, and certainly not our little yellow 2CVs from the PTT. Sometimes, fortunately, there are people who don't obey orders .

The Curse of Front-Wheel Drive

And then there's this tragic irony that gives me chills every time I think about it. Pierre Michelin, killed in 1937 at the wheel of a Traction Avant. Pierre-Jules Boulanger, died in a Traction Avant accident on November 11, 1950. The same car model that took out two giants of the French automobile industry.

Imagine the state of André Lefèbvre, the engineer who designed these cars. Seeing his creations sweep away those he admired... it must have haunted him all his life.

The evolution of the postal vehicle fleet

But the PTT was never just about the 2CV. Oh no, there was a whole automotive epic ! Renault 4Ls took over, Citroën HYs for large parcels, Peugeot 403s, Simca Aronde, Panhards...

And later, in the 80s and 90s, Citroën Saxos, Peugeot 106s, Renault Clios. Each era had its models, but always with this constant: the yellow color that stands the test of time .

I like to imagine our French roads through the decades. In the 1950s, those little yellow 2CVs bumping along the dirt roads. In the 1970s, the Renault 4Ls climbing hills in first gear. In the 1990s, the small city cars slaloming between the ever-increasing number of cars.

The Belgians and their luxury 2CVs

Oh, and then there's this Belgian anecdote that makes me smile. In 1957, the Belgian post office ordered its 2CV vans in "luxury" versions called 2CV AZUL . Produced exclusively in Belgium, with a particularly meticulous finish.

So while our French postmen were content with their basic 2CVs, their Belgian colleagues were driving top-of-the-range versions! Even the austere 2CV could have its premium variants . Who would have thought?

1991: The end of an era

And then came 1991. The PTT administration, officially created in 1925, was in its final stages . It was divided into two entities: La Poste and France Télécom. It was the end of an era, the end of the PTT that had accompanied the modernization of France for nearly 70 years.

It makes me a little nostalgic. These PTTs were a French institution, a symbol of public service and proximity. Those little yellow 2CVs were our countryside staying connected to the world .

Today, when I see a postal vehicle go by - still yellow, faithful to tradition - I tell myself that this color carries within it five centuries of history. From the Austro-Hungarian Empire to the rounds of our modern postmen, passing by the little 2CVs that revolutionized our countryside .

The eternal legacy of postal yellow

This story particularly touches me because it shows how the automobile can transform a society. The PTT 2CV wasn't just a delivery vehicle, it was a tool for social cohesion . It allowed our countryside to not be forgotten, to remain in the movement of progress.

And this yellow, this very special color, continues today to remind us that behind every technical choice, there is a human story. A story of visionaries like André Citroën and Pierre-Jules Boulanger, of disobedient engineers like Henri Loridont, of thousands of anonymous postmen who have crisscrossed our roads .

So the next time you come across a yellow 2CV—whether vintage or miniature—remember this epic. Remember that this little car helped write French history, one letter delivered at a time.

Because ultimately, that's the magic of vintage cars: each vehicle tells the story of an era, each color has its own story, and each road traveled helps build our collective memory .
