Papier collé (French: pasted paper or paper cut outs) is a type of collage and collaging technique in which paper is adhered to a flat mount. The difference between collage and papier collé is that the latter refers exclusively to the use of paper, while the former may incorporate other two-dimension (non-paper) components. As the term papier collé is not commonly used, this type of work is often simply called collage. Papier collé is sometimes also used to refer specifically to the paper collages of the Cubists.
