In the April 1992 case of Art Rogers v. Jeff Koons, Koons infringed copyright in his work String of Puppies which was a three dimensional color copy of a photographic original of Rogers' that he found on a postcard in a tourist shop. The sources I have researched question the boundaries of art and when it is and is not fair use, and in which ways the guidelines can really have a great effect in shaping this gray area. Koons is sometimes referred to as an appropriation artist: an artist who quotes elements from other works and creates a new version of the original. In the case I choose to focus on he does not alter the change enough, it is arguably an exact copy of the original with minor changes. I use a later case in Koons' career - Blanch v. Koons - as a source to highlight what is fair use, and the development of our understanding of it. In my final paper I would like to use this as a comparison. Identity and Koons' call to parody are also central to the fair use argument and thus I have chosen some sources that discuss these important aspects, as a means to both strengthen and weaken Koons' argument (that his work is based on parody).
