Yesterday, I received in the mail my grandfather's cloth escape maps of France, Holland, Belgium, Luxembourg, and Germany. He flew a Piper Cub for the US Army, mainly shuttling brass between England and France. Never used, the maps went from a pocket in his jacket to an envelope in a foot locker; they're in great condition.
Above is a 1:2,000,000 scale map entitled "Zones of France", second edition, and dated "MAR 44". Silk or rayon. I know little about the origins of this one.
It features 4 hand-drawn "placemarks" South of Cherbourg. Positions of forces? Airfields supplied with beer?
I'll be having these framed soon.
