Now online at the New Yorker. This stuff doesn't stay available forever, so go read it.
I have mixed feelings about the lack of originality in a lot of Banksy's art. But his persona and story are pure gold, and I have no problem with the lines he walks - financial success|rebellion, celebrity|anonymity. Favorite quote:
“I originally set out to try and save the world, but now I’m not sure I like it enough.”
The only truly deflating ending to this story (and it will end someday) would be if it turned out that Steve Lazarides, his agent/gallerist/spokesperson, really turned out to be him.
