We've already mentioned that Banksy is spending some time being his incognito self in NYC this month. Earlier this week, he sold original and very valuable pieces of his work through a street vendor for bargain basement prices. (Wish I got my hands on one of those, but know damn well even if I walked past the booth I wouldn't have bought anything so I will refrain for being upset with myself. Good for all the jerks who cashed in. Jerks.) Yesterday, Banksy was at it again, this time painting a touching tribute to 9/11 and the Twin Towers on a building in TriBeCa. (Why can't that just be spelled "Tribeca?") Photos above and below.
