Vignelli Transit Maps describes the history of the New York subway maps and follows this city’s transportation growth from separate, independent lines to one large system. Peter Lloyd uncovers the history of the Vignelli map that includes the legacy of the people who created and promoted this New York icon - as well as those who hastened its demise. He explores in fascinating detail Vignelli’s dealings with the MTA when he was a principal at the design agency, Unimark, and provides profiles of the diverse players, their contributions and conflicting philosophies. The book includes a first glimpse at original, early development sketches of the famed map and of its recent successors, as well as Unimark’s development sketches for the then new Washington DC metro.
