Picasso met Fernand Mourlot in October 1945 after much encouragement from Henri Matisse and Georges Braque. As they predicted, Picasso soon became obsessed with the possibilites of lithography and amazed the Mourlot team with his artistic audacity and talent. Asked by Mourlot how many assistants Picasso needed his answer was, “None. I’ll do everything myself!”. He proceeded to make many innovative experiments on the limestones. Fernand Mourlot characterised Picasso as someone who “looked… listened…did the opposite of what he had learnt”. He would stay at the Mourlot print workshop for several months at a time, 12 hours a day, and over the course of 20 years he created nearly 400 lithographs.
