Even today, when the whole world has been mapped by GPS, there are still valuable hidden treasures left to discover. After calling in auctioneers, the grandchildren of entrepreneur Roger Baillon discovered that the collection of 60 vintage cars from the 1930s to the 1950s left to rust in sheds on the family’s farm in western France could be worth £12 million or more at auction.

These aren’t your run-of-the-mill 1930s old cars, either (if such a thing exists). One Talbot-Lago in the collection had previously been owned by Egyptian King Farouk and a Ferrari had been used in the filming of a movie with Jane Fonda. Along with the rare cars such as the Maserati in this collection, Baillon had intended to build a museum with his classic car collection. When things didn’t go as expected, however, he had to sell 50 of these supercars, and the rest of the collection was forgotten.

The car collection will be put up for auction in Paris on February 6th, 2015. Any of the cool cars unfit for restoration will be sold for spare parts.

This sort of thing doesn’t happen often enough! I think, above all, you go into this profession for discoveries like this. Yes, this really is a treasure,” said Artcurial Motorcars manager Matthieu Lamoure

I have to say that when we arrived here, we found ourselves overcome with emotion. Probably much like Lord Carrington and Howard Carter, on being the first person for centuries to enter Tutankhamun’s tomb. It really was a case of waking up sleeping beauty

Pierre Novikoff, a senior specialist at Artcurial, said, “this was somewhere between a metallic graveyard and a museum. Nature had taken a hold, over the years. Ivy had invaded a car and entirely covered its wheel, while weeds had taken root in a passenger compartment as easily as in a greenhouse

We were standing in front of the Baillon collection. It was thought that everything had been sold, and its existence had been forgotten about. And here, we had just found the lost collection!

Certain cars, much like paintings or sculptures, are works of art, created by artists! Not only the engineering, but their styling reflects the history of design

Every example has been carefully documented by historians and this one was thought to be lost. We have found it!” explained Lamoure.
