A lot of people think that the 1932 photo Lunch Atop a Skyscraper (the one with the guys eating lunch on the beam in midair) was taken during the construction of the Empire State Building. It wasn’t. Those guys were actually at work on the 69th floor of this skyscraper, which for decades was known as the RCA building, and is one of the most famous addresses in New York City. What building is it?

Answer: 30 Rock
