When the real Banksy set up a humble Central Park stand, selling canvases for $60 each instead of the tens of thousands they were worth, he sold just three paintings. A week later, the not-at-all-genuine article fared much better. Artist, author, and prankster Ken Circelli set up a stand at the exact same spot, selling knock-off Banksys for the exact same price, the New York Post reports. "Fake Banksy" the sign on the stand clearly read, and each piece came with a "Certificate of Inauthenticity." Circelli says he sold all 40 pieces in an hour, "including the price sign."
