Local street art aficionados are abuzz today after two Banksy pieces were spotted in San Francisco: one in the Mission, one in Chinatown. Erin Archuleta spotted this fresh piece on Valencia between 19th & 20th above Little Otsu. And caughtyouhoney snapped this piece in Chinatown.
Nifty, eh? That is, assuming that these are, in fact, his work; it's hard to catch the British street artist in action. (Spots Unknown argues yes, these are the real deal.)
Back in 2007, if you recall, SFist sister site Londonist spotted the elusive graffiti artist on the job.
