Here is a map of all the locations from Better Out Than In, Banksy’s October 2013 residency in New York. I’m not sure how many of these are still up. I know some were painted over almost immediately but others have been protected with plexiglass.
I’m not a New Yorker, and I’m worse with the names of New York neighborhoods than Banksy was. Gothamist and Untapped Cities both had good real-time coverage, so that’s where most of these locations came from.
