8. Barbara Kruger, Hoepker V. Kruger
A well-known German photographer sued American artist Barbara Kruger for her use of a photograph of a woman with a magnifying glass. Kruger cropped and enlarged the image, and then superimposed three large red blocks containing words that read, “It’s a small world but not if you have to clean it.” Given that the photograph was in the public domain in the United States, the artist subsequently won the case.
