Thought you knew all about Picasso? Well, it seems there are still hidden secrets out there waiting to be found.
Restorers at the Picasso Museum in Barcelona pulled out the cardboard behind a painting of his mother he had drawn aged 15 and found an even earlier work, a charcoal drawing of a man smoking a pipe.
It seems the world famous artist produced amazing works even earlier than previously thought. The work is part of a collection of 921 works that Picasso gave to the museum in 1970, most of which he created when he was young.
