British stencil artist Nick Walker—whose name was recently floated by a leading website as a plausible answer to the question "Who is anonymous international superstar street artist Banksy, really?"—has been a busy man. Not only was he spotted painting a piece on the side of Thunder Jacksons in the West Village—which sparked all this Banksy speculation in the first place—he also did quite a nice giraffe-themed work on the side of Roebling Tea Room in Williamsburg. We're still trying to pin down the true nature of the Banksy-Walker connection, so if you happen to have spotted Walker at work, email us. After the jump, two larger pictures [via Williamsburg is Dead] of the towering ruminant.
