Lost 70s MTA Typography Manual Archived Online
An accidental discovery in an old locker revealed the long-lost "style book" for one of the world's most recognized and iconic graphics projects, the entire "look" of the New York City Metropolitan Transit Authority since 1970. The Unimark company and designer Massimo Vignelli came up with the system of colors, shapes, and typefaces for all the elements of mass transit in NYC, and now the full manual has been scanned and posted, page by page, online.
The 1970s manual, designed by Massimo Vignelli and Bob Noorda of Unimark, includes all the typefaces, signage and official color design that New Yorkers have come to know so well.
