Montage – The technique of combining in a single composition pictorial elements from various sources, as parts of different photographs or fragments of printing, either to give the illusion that the elements belonged together originally or to allow each element to retain its separate identity as a means of adding interest or meaning to the composition.

David Hockney is a painter, draughtsman, printmaker, stage designer and photographer. Cubism is like montage in the sense that it is a collection of little pictures to make a bigger picture.
