Representational Art is any type of art that represents the physical world, however naive or stylistic that representation may be. Picasso's distorted and sometimes disjointed view of the world can not be described as abstract; it remains representational throughout. Many artists of the 20th century developed approaches that emphasised design and colour above perspective and form. The earliest innovators were the Fauves (see Post-Impressionism), who included Matisse and Dufy, and the cubists; Picasso, Braque, Gris and Leger.
Perhaps inspired by the madness of the First World War, the Surrealists, were another influential group; Salvador Dali being their most famous member, although he left the group after only a short time. The Expressionists were another European movement who explored the human psyche as well as the physical world; Munch, Klee, Macke, Klimt and Marc are associated with expressionism.
A more realistic approach can be found in the post-war paintings of American's Georgia O'Keeffe and Edward Hopper. Hopper's work often presents a rather ironic view of the American dream. In the 1960's the pop art movement under the influence of Warhol, Lichtenstein, Johns and others also took contemporary society and consumerism it's suject. In Britain pop art's leading proponents were David Hockney and Peter Blake.
