1927 "UNDERGROUND RAILWAYS OF LONDON - KEY SHEWING UNDERGROUND RAILWAY CONNECTIONS WITH MAIN LINE TERMINI"

On this edition of the Underground map the River has been shown as a less obvious feature, using thinner lines for shading. The reverse of the map has a further less detailed map showing the Main Line Connection Termini & Interchange Stations. Each Underground line is shown by a different colour and interchanges are represented by a circle in the line colour. The District Railway, Bakerloo and Metropolitan Railway lines are not shown in full, and stations beyond the boundary of the map have their names in a box indicating the continuation of the line. The map has the title 'UndergrounD Railways Of London' and there is a reference key showing line colours. This example was publshed in a Guide Book with one central vertical fold. Overall size approx 15.8cm x 12.8cm. 

Designed by Fred Stingemore (1890-1954) who was a lifelong employee of the Underground Electric Railways Company, UERL, (1902-1932), and then the London Passenger Transport Board (from 1933). He worked first as a draughtsman in the Publicity Manager's Office, which issued this map, and then as head of the Commercial Drawing Office. Stingemore's first map of the Underground was issued in 1925 and then reissued with revisions several times until it was superseded by Harry Beck's design in 1933
