Explanation:

Collage is an artistic technical procedure of using various materials that may or may not vary the texture, one over the other or side by side, forming a motif or a new image.

Collage as a technique has its origins dating back to ancient history, however its artistic value was recognized from the twentieth century, with its use in Cubism, before that it was considered either child's play or popular artistic manifestation and lacking critical foundation. The use of various materials on a support, such as wood, newspaper pieces and objects, makes collage a technique that questions the boundaries between painting and sculpture.
