From the "People at Work" series, this copy of The Soldier, first published in 1966 and written by I and J Havenhand with John Berry's wonderful illustrations, dates from about 1974 and is in good overall condition.
The Soldier describes all the varied roles within the army such as the Catering Corps and the Parachute Regiment and makes for a wonderful read for all ages; ending with the beautifully innocent paragraph:
"Soldiers are well-fed and well-clothed and are always with their friends. They have busy lives and are happy men."
This book would be a superb gift for the squaddie in your life.
