This is a very early WWII silk escape map, issued to RAF airmen to assist them in evading capture should they be shot down over enemy territory. This is one of the earliest such maps issued by the British military intelligence unit (MI9). Known as a Bartholomew map because it was derived from a cycling map produced by the famous Bartholomew map company of Edinburgh. The main map, numbered 9.C.(a) in the lower right border, covers France and is printed in three colors: map details in black, roads in red, and international boundaries in green. The map on the verso, 9.U, is printed solely in black on a white background. If you care to learn more about the history of these fascinating maps here is an excellent website.
