Oh, happy day! Banksy, the most famous of all British street-artists, has been putting up new work in Williamsburg. So far, we've spotted these shots on Flickr-- but please, if you see any others, send them in to photos@gothamist right away.

A little more info on Banksy: his official site, some recent Banksy work in NYC and LA, and the Wooster Banksy archives.
