Midtown Manhattan commission finished

This 22"x28" painting is of a historic 10-story building on Madison Avenue near Grand Central Station. Unfortunately because of high rise buildings built around it, the sun rarely hits it. Let's just say that I used artistic license (couldn't say "historic perspective" because of the yellow cab and SUV) to have sunlight drenching the Madison Avenue side of the building! I worked from several photos that I took, as well as archival photos and architectural drawings that were made available to me. Can anyone guess what business is in this building?
