For decades, artists have created appropriation art — works that place pre-existing photographs, images or objects created by others in new contexts. Examples range from Pablo Picasso’s Bottle of Vieux Marc, Glass, Guitar and Newspaper, a 1913 collage including newspaper clippings, to Andy Warhol’s 1962 work Gold Marilyn Monroe, an iconic silkscreened

photograph of Monroe on a gold background. Appropriation art poses difficult challenges for copyright law, because copyright rewards the creativity of the appropriation artist, but includes broad prohibitions on the use of creative works made by others.
