Key Cubist works included Picasso's 1907 painting Les Demoiselles d'Avignon. The document then provides brief overviews of additional artists such as Calder, Klee, Escher, Matisse, Lichtenstein, Warhol, Rothko, Walker, Orallo, Sobrado, and Okuda San Miguel who incorporated distinctive shapes into their artworks in various styles.
