3. 20 Exchange Had a Heck of a Ribbon Cutting


According to the New York Times, its February 24th, 1931 opening saw “an hourly average of 3,851 guests… during business hours.” At an 8-hour day, that’s over 30,000 people at the opening. To put that in perspective, the Empire State Building sees about 10,000 visitors in a typical day.

To give an additional sense of the importance of 20 Exchange, some of the lobby doors feature miniature versions of the skyscraper (as above).
