Maps Hidden Behind Calendars?

Discussion in '1940' started by Karen D McIntyre, Mar 28, 2019.

  1. I just finished reading an account of Capt. Christopher Waters' escape across France and Spain in 1940. In it, he states that maps were concealed behind calendars in French estaminets. This is the first I have heard of that. Does anyone know if it's true?
