Supports/Surfaces was a short-lived French movement of the late 1960s and early 1970s, formed in the south of France by artists from the Montpellier School of Fine Art and the Paris École des Beaux-Arts. In the political wake of May 1968 they combined Marxist thought with a material deconstruction of painting: the canvas and stretcher bar, which normally disappear behind the image, were made the subject. Group shows began with Impact 1 in 1966; the first exhibition titled Supports/Surfaces opened at the Musée d'Art Moderne in Paris in September 1970; internal dissension split the group in 1972. As Claude Viallat summarized it, Dezeuze painted frames without canvas, he painted canvases without frames, and Patrick Saytour painted the image of the frame on the canvas. Shown in fields, on beaches, and in streets, and theorized in Peinture-Cahiers Théoriques, the movement stayed little known outside France until recent retrospectives.
