A large map designed by the team at Geographia, and printed by the Baynard Press. It shows the routes of London Underground in a geographical layout, and not in the diagrammatic 'Beck' format used for the smaller pocket maps from 1933.
This map was produced just before the beginning of the second world war and used a design that had already been in use for a number of years.
It is a folding map and has fold lines.
