Both a love letter to New York City & an introduction to graphic design, this is the story of how the designer Massimo Vignelli tackled the problem of creating a subway map that could be understood by all New Yorkers as well as out-of-towners. Filled with depictions of trains, subway stations, & the New York City skyline, the book follows Vignelli around the city as he tries to understand the system in order to translate it into a map. The book is produced in collaboration with the New York Transit Museum & features a section of historical & archival images & photographs.A groundbreaking work of information design, the subway map designed by Vignelli is an iconic work used by over a billion people every year. The Museum of Modern Art acquired the original 1972 diagram in 2004.
