Collage art is a form of art that combines various materials such as newsprint, fabric, and photographs to create a unique image. Collage artists often rely on a variety of found objects and images to create their work. This type of art has its roots in Cubism, which emerged in the early 20th century. Cubist artists such as Pablo Picasso and Georges Braque began experimenting with collage techniques as early as 1912. 

Collage art became increasingly popular in the years after World War II. Many artists began using everyday objects in their work as a way to comment on the materialism of Western culture. The Pop Art movement also made use of collage, with artists such as Andy Warhol incorporating images from magazines and newspapers into his paintings. 

In the 1970s and 1980s, Punk Rock culture also made use of collage, with album covers and flyers often featuring ripped-up images and bold, blocky text. Collage has also been used in film, most notably by experimental filmmaker Stan Brakhage. In recent years, many digital artists have begun creating collages using Photoshop and other digital software programs.
