Notes
The third folding pocket-version of Harry Beck's revolutionary tube map, based on electrical diagrams. The first issue of his new design was in January 1933, and minor tweaks were made for subsequent printings. In this one, with print code '33-2791', the interchange stations are marked by the familiar circles, instead of the diamonds of the initial design, and the escalator connection between Bank and Monument stations is noted for the first time.
