Pablo Picasso was one of the most important leaders of cubist art movement. Picasso was a Spanish painter as well as a sculptor. Cubism is when subjects and objects are broken up into pieces and rearranged in an abstract form. Picasso had a strong impact on the art world; there had never been any artist prior to Picasso that influenced the art world as much as he did. His value has only increased since his death in 1973.
