Swiss ambassador Bruno Spinner asked a group of graffiti artists in 2001 to help deal with Switzerland’s public relations nightmare: i.e. Swiss Banks held Nazi Gold in World War II. Spinner recruited a group of graffiti artists to create new works in the Swiss embassy car park as a sort of image makeover, and the artists were permitted to have a rave. The Guardian today reveals that one of the little-known artists was Banksy, and that his previously secret art in the car park is now valued at over 1 million English pounds.
