In recent years, the production of multiples from an original work of art, especially fine art prints, has become a major business in the art world. What distinguishes a mere poster from a valuable, collectible, fine art print, is usually the scarcity and quality of the work in question. In other words, prints that are produced using high quality materials, hand signed by the artist, and sold in a limited edition are likely to be more collectible (and thus have higher resale values) than posters that are produced using low quality, inexpensive materials, unsigned by the artist, and ubiquitous.
