There was a Banksy show in Los Angeles not too long ago. There was one in San Francisco, too. Shows opened in  Atlanta, Warsaw, Dubai, London and NYC and countless other cities around the world. They are not real, mind you, or sanctioned or authorized by the artist. When one of these unsanctioned shows made its way to South Korea, visitors in Seoul rightfully demanded their money back, complaining that there weren’t enough authentic Banksy works in the exhibition. It’s like there was a world tour of Banksy shows, but the star of the show wasn’t even on the tour bus, so to speak.
