During these years, Picasso was forbidden to exhibit his art, which was considered too degenerate under Hitler’s new art policies. He kept on working but was constantly running out of supplies. This new dilemma forced him to seek some innovative new approaches. Instead of focusing on his paintings, he began to work on sculptures. He created sculptures using any material he could lay his hands on—a broken piece of metal, an old cigar box, a bike handle. His well-known Head of a Bull was made of pieces of bicycle material.
