Apparently produced for the 1939 World's Fair, this "panoramic" map of New York has a weird perspective, both visual and historical. Various neighborhoods, landmarks, and structures are noted (the McGraw-Hill building gets a shout-out). Its best feature, though, is the "Ghetto" label over the Lower East Side. So much changes over the decades, and so much stays the same.
