Back in 1978, Massimo Vignelli and John Tauranac debated the future of New York’s subway map. That debate—which in many ways never quite ended—is now the subject of a book coming out later this month. Edited by Gary Hustwit, The New York Subway Map Debate includes a full transcript of the debate and subsequent discussion (thanks to the discovery of a lost audio recording), plus contemporary photos and new interviews. Paperback available for $40 via the link.
