The upper image closely resembles a 1940 painting, Cheltenham Fantasia, which was sold to a Mr Anderson at the Leicester Galleries in March of that year. The lower image is a study for Piper's 1940 Curwen Press auto-lithograph 'Cheltenham', produced while he was also working on illustrations for the Shell and BP Shilling Guide to Gloucestershire (1939; not used in the project). Betjeman, then head of the project, also used the image to illustrate his article "Book Illustration Can Colour a Whole Town or City" in 'Signature' in 1940. The Cheltenham design is covered and reproduced in Hugh Fowler-Wright's book on Piper.
