A small San Francisco store and gallery, Park Life, was served a cease-and-desist letter from Jeff Koons's lawyers for selling a set of bookends that resemble the artist's large, metallic “Balloon Dog” sculptures.

The store removed the bookends from its inventory, posting on its blog, "...Jeff Koons owns all likenesses of balloon dogs.” A few days later, the bookends reappeared on the store's shelves with a note that they would be back in stock soon.
