Two OSS maps of the European Fronts; the first for the week ending January 30, 1945 and the second for the week ending February 20, 1945. Both maps show the status of Allied advances and German and Allied operations for the time period noted. Both are marked restricted at the bottom center of the map and the top right corner of the page. The January map was eventually stamped "unrestricted". The Office of Strategic Services (OSS) was a wartime intelligence agency of the United States during World War II, and a predecessor of the modern Central Intelligence Agency (CIA). The maps measure 18.5" x 17". excellent.
