Underground maps after Beck – Maxwell J. Roberts Snelle Levering

This account of Harry Beck’s London Tube map, a companion to its predecessor, Mr Beck’s Underground Map, charts the evolution of the famous journey planner from the 1950s to the present day. With colour reproductions and insightful commentary, it navigates a wealth of surprising changes to Beck’s original, including new symbols, lines and zones; the ill-fated inclusion of parks and rivers; and some bizarre attempts at ‘modernization’ which luckily never caught on.
