1 march 1968 & metro mapped/named

#OTD Thursday 1 March 1968 WMATA officially adopts this 97.2 mile regional map. In addition to officially adopting the map, the name, Metro, was officially adopted. According to scholar Zachary Schrag, we can thank Massimo Vignelli, an Italian graphics consultant, for Metro, which is short for Metropolitan. Also, "Vignelli gave Metro a symbol: a capital M in the Helvetica typeface, to be printed, embossed, and emblazoned on trains, stations, uniforms, and pylons throughout the region."
