In developing his own approach to modernism, Léger assimilated aspects of numerous styles. His work before World War I could be considered Cubist, but his post-war work had the modern, hard-edged, machine-inspired aesthetic of Purism, an art movement promoted by painter Amédée Ozenfant and painter/architect Le Corbusier. In Yellow Composition, Léger returned to the city theme he had treated repeatedly in previous works. This time, however, he playfully combines the rectangular forms of architecture with the organic tendrils of a vine.
