Non-Pocket Underground maps

• American Red Cross

  The American Red Cross issued a series of leaflets for American forces stationed in London during the Second World War, which included maps of the underground railway. Of particular interest is the circa 1942 edition, which shows the north-eastern branch of the Northern line distorted to allow for the planned Northern Heights extensions of the Northern line. The work on these extensions was started but abandoned. For a while, the extensions had been shown as broken lines, but by 1942 they had been deleted. This, however, left the diagrammatic map of the Northern line with some curious bends, which were later ironed out. This circa 1942 edition was not used in the pocket maps.
  

• Geographia

  Shows use of interchange symbol comprising circle with central dot, in approximately 1940. This graphical device was introduced into the pocket maps by Paul Garbutt in 1964, so it is interesting to see it used this early. Although the map is essentially a Beck design, it is believed that the interchange symbol was the handiwork of someone else.
  

• Miniplan

  Beck-style map including Victoria line. Harry Beck was discharged from looking after the underground map in 1960. Subsequently, the Victoria line was added, but his suggestions were ignored. Miniplan Ltd published these maps of London, including Beck-style maps of the Underground, but with the Victoria line independently added by an anonymous draughtsman.
