it's on church street, stoke newington, london, uk. outside the vortex jazz bar. I work about twenty metres away from it!
that corner has a bit of history. First it was claimed by RD crew, then banksy dropped a nice stencil of the guard pissing ink onto the wall, then shogi (rd) did a throwie over it, then banksy did one of the biggest stencils ever on it, then welsh and shogi wrote on it..
banksy's turn.
