Wow if his stand was near MOMA I probably walked right by it yesterday without noticing... I usually just ignore vendors around the park because 99% of the stuff being sold in that area is mass produced crap that has no value but to extract money from tourists.
Well, also...he's messing with the people who value his stuff at ridiculous prices, but can't pick it out of a lineup.
This is great not because it was anonymous (that was just a requirement -- if it weren't, he'd have been swamped by idiots), but because it illustrates the fundamental absurdity of the art "scene". It's a nice bit of mockery.
If you listen to his audio commentaries (most of his pieces in http://www.banksyny.com/ have a commentary on the page), he pokes fun at himself and at pretentious commentaries that often accompany art pieces.
