Here is a stencil on a board. I pass by on Fillmore on my way to the market.
Here is a stencil I saw on the side of a building in the Mission. Simply says, "Gentrification Even Better Than Cocaine"
I passed this Obey wheat paste on Market. I think it was done last month when Shepard Fairey was in town for an exhibit. I saw a wall near the gallery that was killer. I'll try and get a photo.
