Banksy's Evil

Banksy keeps coming up with new ways of displaying his art. Somewhere along 23rd Street in New York there is a thrift store containing this oil painting on canvas The Banality of the Banality of Evil (2013) (CLICK). My guess is that this was one of those unoriginal paintings churned out by Chinese artists and exported to the West for punters who want a nice oil-on-canvas landscape at a knockdown price. It's almost a factory process in China. The same artist paints the same picture day after day until he can do it with his eyes shut. That's how the prices are kept so low. Banksy buys this painting in a thrift store, paints the Nazi sitting on a bench enjoying the view, then re-donates his "vandalised" painting to the same thrift store. It's now worth a fortune as a Banksy, but will anyone have spotted it?
