Provenance:British Museum-Purchase receipt copy included. In 2005, the artist Banksy installed a piece of concrete in the British Museum’s Roman Britain gallery. A bison, a person who looks like they have spikes protruding from their back, and a supermarket shopping wagon are drawn in marker on the concrete. Entitled “Peckham Rock,” the installation mimicked standard museum practice with a label that had a title, description, and even a fake identification (accession) number. The label read, “Peckham Rock” remained in the gallery for three days until museum took it down when they learned about it through Banksy’s own website.
