Maps used to persuade
This 1941 map by Jean Fort depicts U.S. President Franklin D. Roosevelt and U.K. Prime Minister Winston Churchill in a tug-of-war over Africa. It was made for the German propaganda unit in then occupied France. It is one of 13 examples of the use of maps as propaganda curated by National Geographic. They are all currently hung in an exhibition called 'War Map' at the Map House in London.
