Neat large Admiralty Chart D Shewing (sic) Patrol Areas around the British Isles. Measuring 14.5” x 20” (37cm x 51cm) and printed by J D Potter, can’t find any date on it, but I would assume WWII era? As you can see by the pics, it’s printed on fine paper, and has been folded, I’m sure the folds could be ironed out and it would look great framed. Please see pics for full details. Thanks for looking 🙂
