Yesterday we mentioned a possibly Fakesy up at 6th Avenue and 24th Street, but the piece is real... at least according to the 1-800 number that's been tagged by all of his pieces so far. A reader dropped by this one and it turns out the number is there—when called, if you press #2 the voice on the other end tells you: "Are you looking at one of the great art works of the 21st century? If so, you're in the wrong place. You should be looking at a stencil of a dog peeing on a hydrant."

The narration goes on, saying, "It's a well known truth that the mark of a great artist is his ability to capture light..." he then mentions how this is a silhouette, discusses cartoons, and says, "welcome to the art world." After that it gets almost impossible to hear.

Some spotted the new piece as early as 8 a.m. yesterday, and one commenter noted that the number was there at that time, so it's unlikely it was added by someone after. The recording mentioning the piece seems to have only been put up more recently, however.

The new piece hasn't appeared on the BanksyNY Instagram, where the previous pieces have been posted after they were put up.

UPDATE: Jen Chung is on the scene and has sent in some new photos, showing that someone has now tagged the dog. There's also a blue stencil next to the hydrant.

UPDATE, 9:15 a.m.: Just after 9 a.m., over 24 hours after the piece was first spotted, BanksyNY has posted the piece on Instagram...
