This blanket term describes the type of collages that emerged when hands and arms were choreographed within the photobooth to create specific shapes in response to a pre-ordained drawn cartoon. Rideal pioneered this technique first in Identity, other portrait work followed, then Magic Carpet, Adam & Eve (a pair of skeletons) and a riff on Mondrian’s Red Tree 1908 and Composition in Red, Yellow and Blue 1921.
