Tri-fold passenger map of the London underground, 11 x 15 cm, printed in colours on linen backed card, minor edge wear, a trifle soiled, gold on covers dulled but black text remains sharp and clear. Vertical ‘UndergrounD’ logo on cover (more often seen outside stations than in print).
This example, unusually, was issued by the Metropolitan Railway, which was not part of the Underground Group. The Central London Railway extension from Bank to its new terminus at Liverpool Street is shown as under construction on the map, so the period between July 1910 and July 1912 is the likely window for the printing of this edition. The cover carries advertising for the 1911 model Ariel motorcycle, which could be seen at the new Olympia Motor Cycle Show held in November 1911; an international Motor Show was also held at Olympia that month.
The format is the archetype of the series of folding pocket maps designed by Fred Stingemore in the 1920s, opening to reveal three panels, and the direct ancestor of the maps given away at stations today. Leboff and Demuth, ‘No Need to Ask’, p. 56
