During the 1920's, a sense of unease began to appear in Picasso's work. He started coming away from the abstract style and closer to the surrealism style. His pictures were still abstract looking, but looked closer to the real thing. Picasso's marriage ended in 1935. Pablo had made a model of Marie Therese Walter.
People say that that's why their marriage ended, but nobody if it is really true.
Pablo and Olga never got a divorce. But, Olga died in 1955. After a while, Picasso left public activity, and Paris. He started to spend more time in France. He moved to Antibes in 1946.
