These maps were designed and drawn by Frederick H. Stingemore (and signed FHS in the lower corner) in eleven editions from 1925 through 1932. They were printed on stiff, linen-backed, tri-folded card (at first 6 × 5 inches, later enlarged to 6½ × 5½ inches). The whole of the inner surface is taken up with a colourful map that is still geographic but is nonetheless somewhat abstract. All background detail has been dropped, and the network is shown as colour-coded lines which have been distorted to fit into the available space. The outer surface is coloured linen, with the left and right panels containing informative text and the middle panel serving as the front cover.

The Stingemore maps were designed to be carried out around by passengers in their pockets. They are of a handy pocket size, robustly made, with a durable material on the outer surface. In their trifolded format, they could very quickly be folded and unfolded while on the move. This is in marked contrast to the earlier thin paper maps that really needed to be spread out carefully on a desk. This represents a significant shift in the conception of how the maps were to be used: from pre-journey planning to in-transit navigation.

Another significant feature is that—from the fourth third edition onwards—the outside back cover of the map card contained a list of theatres and the nearest Underground station to each. This list was scrupulously updated as new venues opened (and occasionally closed), and as stations closed for refurbishment. The implication is that one of foremost uses of the map was for better-off patrons to find their way to the theatre in the evening. Until the 10^th edition, the inner cover panel also had a list of Places of Interest but this (rather than the list of theatres) disappeared from the next edition when space was needed to announce changes to the Underground network.

The maps underwent very little stylistic change over the seven years, in marked contrast to the volatile designs of the paper maps from 1908 to 1928. Only the first four were issued with a date, or even a datable reference code. Dating of the others must rely on clues in style and content.

Some Stingemore maps were printed on thin paper, in the same size as the cards. These were normally distributed as a glued-in insert into a guide to London.
