A scarce to very rare wartime Penguin book, 'Signalling and Map-Reading for the Home Guard with advice on improvising equipment' was written by H.G. Stokes and published in 1941. The front cover is in the classic Penguin style. 128 pages of text and diagrams. The book is in very good condition for its age and shows no damage. Someone has put a signature in pencil in the top corner.
