A slab of stone painted by Banksy in Berlin is up for auction on Ebay. Sprayed by the elusive artist in 2003, the stenciled rock features a rat painting an “A” for anarchy. The 80-pound painting was once situated on the side of a building at a military graveyard before being cut down, with permission, for preservation and profit. The owner of the auction, currently at $4500, not only offers to help hang the piece of wall, but also cleanse it of several stenciled cowboy heads painted by lesser known vandals.
