Here, in chronological order, a roundup of historical, replicas and future iterations of the New York City subway map. Until the 1940s, the subway was run by three competing companies: Interborough Rapid Transit (IRT), Brooklyn-Manhattan Transit (BMT), and the Independent Subway (IND). Watch the lines spread like a vine over the geography of the city, see the system unify into one beast, and observe how graphic design evolves with the aesthetics of the decades. These maps and many more are available here, at
