Art prankster Banksy has been at it again. This time at the British Museum with prehistoric art: "early man venturing towards the out-of-town hunting grounds". Done on fake rock, plus suitably authoritative caption. BBC picture of Caveman with a Shopping Trolley and story here.
Thanks, Lincoln + Ron M!
In March 2005, Banksy visited NYC's most famous art museums. See photos of a 'British pensioner' in action and results here.
