Is the tourist sidewalk line that suddenly showed up earlier this week actually a work of Banksy? A tipster pointed us to Banksy's book Wall and Piece, which has several examples of his text work, which bear some resemblance to the sidewalk lane (you can see some of those examples above). Banksy pieces have been popping up all over the city during the past week since his arrival in NY, and the sidewalk line has simultaneously become the "talk of the internet."
