Looking Up

Cool up arrows graphic on the side of this Midtown East building. I'm not sure you can even see this from the ground, as there might be another building adjoining this one for it's lower half. Anyone know what building this is- it's around 3rd Avenue and maybe 45th Street? This is 747 3rd Avenue- designed by Emery Roth & Sons and built in 1972. Cool aerial shot here.
