1922 Map showing the under/overground network around Liverpool St, Fenchurch St and London Bridge going out in the direction of Shoreditch, Cambridge Heath and Devonshire St.
It is dated 1922 and is in a clean condition.
I don't know the origin of the map... whether it is from a book or a series of prints but a very unusual map which I have never owned before. Mount is 30x22cms. A4 size.
