This book, the first comprehensive survey of the technique, explores in full the theoretical implications and political messages behind the work of the past century, explaining how the process was intimately linked to other revolutions in art practice. It covers the many offshoots of collage, including assemblage, montage, photomontage, and decollage. Along the way it outlines a new vision of modern art springing from this most simple and democratic of techniques. 206 illustrations, 91 in color.
