A comprehensive collection of Underground pocket maps

A run of folding card pocket maps from the first use of the 'London Underground' slogan, through the introduction of Beck's icon 'electrical circuit diagram, to his last contribution published in 1960. The 'UndergrounD' card was designed by F.H. Stingemore (1890-1954). Issued in 1925, it removed all surface detail, including the Thames. His map went through 14 issues before it was replaced by Beck's masterpiece in 1933. Henry Charles Beck ('Harry', 1902-74) produced 38 before being forcibly 'retired' in 1959 (his last effort was published in March the following year), although there was a hiatus between 1938 and 1941. During this period seven cards were designed by 'Zero' (pseudonym of Hans Schleger) Although we are reasonably confident this is a complete run it is possible that an eagle-eyed connoisseur could find a variant edition.
