In 2003, Banksy donated one of his artworks to the Tate Gallery in London. The thing is, the Tate Gallery hadn't actually asked for anything of his. He just walked in (or had a friend walk in, or had a member of the collective walk in--Banksy's true identity is uncertain) and stuck it to the wall. This is just the kind of appalling disrespect that I think the world needs more of.
Over the next couple of years, he made similar donations to the Louvre, the Metropolitan Museum of Art in New York, the Brooklyn Museum, MoMA, the Natural History Museum in New York and the one in London, and the British Museum. At least two of the museums have added these donations to their permanent collections.
It takes a special kind of mind to tag Trafalgar Square with an enormous sign reading DESIGNATED RIOT AREA. Also to sneak into the penguin enclosure at a zoo and leave the message "We're bored of fish." And the Lady Di ten-pound "Banksy of England" notes are incredible . . . too bad he would face 12 years in prison if he actually distributed them.
It's a shame that Batman and Wonder Woman aren't real, but at least we have Banksy.
