Décollage

Décollage, in art, is the opposite of collage; instead of an image being built up of all or parts of existing images, it is created by ripping and tearing away or otherwise removing, pieces of an original image. The French word "décollage" translates into English literally as "take-off" or "to become unglued" or "to become unstuck". Examples of décollage include etrécissements and cut-up technique. A similar technique is the lacerated poster, a poster in which one has been placed over another or others, and the top poster or posters have been ripped, revealing to a greater or lesser degree the poster or posters underneath.
