Some time ago real Banksy prints were sold for $60 at a street stall in NY. They didn't sell much but people who bought one later discovered they are worth around $20,000. A week later some guys (Dave Cicirelli and Lance Pilgrim) sold fake Banksy's with a certificate saying they were real fakes. They sold out in an hour. This was a great way to show the real value of art.
