World's Fair Subway Map

I found this treasure at Park Slope's Fifth Avenue Street Fair over the weekend. It is map of the New York City Subway system published in 1964. See it in all its glory here

While not as iconic as Massimo Vignelli's 1972 map (and 2008 reproduction), it still is pretty interesting to look at. If for no other reason than to see the changes to New York over the last 44 years.
