Collage is the art of “gluing pieces together”. It was made popular by Pablo Picasso and Georges Braque. They used it as a part of the Cubism movement in the early 20th century, but they weren’t the first ones to do so - early collages, made of pieces of paper glued together, can be found as far back as 12th century Japan and China. Collages are universal and can be found in the works of surrealists (who used photographs), abstract expressionists, pop artists, and contemporary artists.
