I was in Williamsburg a couple of weeks ago, and my friend, who's in the picture, told me about this great piece of graffiti a la Banksy that just cried out to be photographed. (My husband says it's Brooklyn's Flat Stanley.) It's actually a piece of waterproofed paper or some similar material, rather than spray-paint on the wall. I'm glad I got the pic when I did -- we walked by 24 hours later and it had been vandalized. Close-up after the jump.
