Here’s another beautiful old London Underground poster that features the Tube map, apparently produced to help servicemen unfamiliar with London get around. The poster, which basically acts as a Tube Map for Dummies guide, was placed next to the map in stations, with the abstract guard pointing towards it. The “tear-away” section at the bottom right shows a slightly modified version (angles aren’t at 45 degrees, the Aldwych spur is missing) of the central part of the map, which would have been the 1943 edition.
The artist was Polish-born Jan de Witt (1907-1991), signed as “Lewitt-Him” on the poster.
