Progress of Collage.

'A collage may include newspaper clippings, ribbons, bits of colored or hand-made papers, portions of other artwork, photographs and other found objects, glued to a piece of paper or canvas. The origins of collage can be traced back hundreds of years, but this technique made a dramatic reappearance in the early 20th century as an art form of novelty.'
