High relief

No, this wasn’t taken in a museum. It’s the side of an incredibly interesting apartment building in New York City. Correction: it’s a small portion of the side of an incredibly interesting apartment building in New York City. The building was on a corner, but every inch of both exposed sides looked like this. It wasn’t a small building either. It looked at least ten stories high.

Can you imagine the kind of work that went into this?

I’m on a mission now to find out the name of the building. I’ve passed it a few times, photographed it every time I had a camera in hand, but I still don’t know what this building is. It’s somewhere close to the Metropolitan Museum. Anyone?
