The Cubism of Picasso, Braque and Gris had more than a technical or formal significance, and the distinct attitudes and intentions of the Salon Cubists produced different kinds of Cubism, rather than a derivative of their work. "It is by no means clear, in any case," wrote Christopher Green, "to what extent these other Cubists depended on Picasso and Braque for their development of such techniques as faceting, 'passage' and multiple perspective; they could well have arrived at such practices with little knowledge of 'true' Cubism in its early stages, guided above all by their own understanding of Cézanne." The works exhibited by these Cubists at the 1911 and 1912 Salons extended beyond the conventional Cézanne-like subjects—the posed model, still-life and landscape—favored by Picasso and Braque to include large-scale modern-life subjects. Aimed at a large public, these works stressed the use of multiple perspective and complex planar faceting for expressive effect while preserving the eloquence of subjects endowed with literary and philosophical connotations.
