Crazy super prankster “Banksy” is at it again, this time with a treasure hunt in The British Museum. The British Musuem houses the Rosetta stone, The Elgin Marbles, and now a piece of rock found outside the building that Banksy has drawn a pre-historic man pushing a shopping cart on. His site says it has remained in the collection for some time now, and they’re offering a prize to the first person to locate the piece of rock and photograph themselves next to it. Trying to remove or alert museum staff is instant dis-qualification. Oh, I love treasure hunts, I wish I was in London! More at the Wooster Collective
