Two AWESOME things happened on this day in history:
In 1931, the greatest building in NYC was opened, the Empire State Building. (Okay, I like the Chrysler Building too, and it's prettier/more handsome in some ways, but it doesn't have quite the same history or recognizability around the globe, unfortunately.)
Ten years later, in 1941, the greatest movie ever made was released, "Citizen Kane". (I know, it's a matter of debate since "Vertigo" usurped CK in the BFI poll.)
