Your body. My choice.

The fact that there is a shadow from the frame on all sides makes me think its edited.

I hope it's the former

As far as I can find online, it's real. Would have to have a New Yorker go to 5th Ave. and 49th St. to verify, assuming it's still up.

I'm not an expert by any stretch, but it looks fairly legit.

You can see the lighting of the picture is similar to the lighting of the scene/world, including some mild reflection of the ground and cars in front of the dark parts of the picture (his black jacket).

These are very subtle details that, while always possible to fake, would have been a pretty serious investment in time and energy to have done.

So I'm inclined to think it's legit.
