on the right is a bookend that was being sold by a store in San Francisco, Koons sent them a cease and desist letter, saying we've got to stop selling this, this is derivative of my work,they said no we're not going to stop and he wisely back down because he basically had appropriated a folk art form,that had been going on for decades before he created sculpture,I think would be very difficult for Koons to present that this was his intellectual property.
