One of the Guernsey stamps in the “Stories from the Great War” set pictured Salvation Army volunteer Ada Le Poidevin. The cover with single stamp is an unofficial cover issued by Rob Kinnon-Brettle (Kinnon Covers). He persuaded the post office to cancel with the official First Day of Issue postmark. Limited edition – only 50 covers were issued!!! Below is the official FDC with full set shown.
