Gawker is reporting that the artist known as Banksy is in town to commemorate the third anniversary of Katrina. Gawker has posted six works allegedly painted on New Orleans' walls. Gawker also notes the Banksy vs. Fred "Grey Ghost" Radtke angle of the work. For more on Radtke, see this piece from Gambit Weekly's Best of New Orleans 2008. The photos of the local work come from flickr pages by three local photographers (one, two, three). They are updating the photos as the each new splash of paint hits the wall.
