Cubism has been one of the most important and influential movements in twentieth-century art. In the eight years between 1906 and 1914, Cubism, and in particular Pablo Picasso and Georges Braque, were to change the technique and form of painting radically and for ever. Originating in Paris, the movement became a truly international force, and one with a profound impact on human visual experience. This book, illustrated with over 300 photographs, presents a vivid evocation of Cubism as a historic and aesthetic force. Douglas Cooper was one of the foremost critics and collectors of his generation. His insights into the work of Picasso, Braque and their contemporaries in the international avant-garde are informed by his close friendships with them.
