The subway map design by Massimo Vignelli was published from 1972-1978. He was invited to recreate the map after successfully installing new subway signage. Both projects feature the Helvetica font, which, along with his map, have become modern design icons. A copy hangs in the NY MOMA and the Met. This colorful, abstract map, or "diagram," as described by Massimo, was originally inspired by Henry Beck's 1933 London Underground map. In 2011, Massimo again teamed up with the NY MTA to offer riders The Weeekend, an interactive digital map based on his original design. For more information, please visit NY MTA Authentication.
