A propaganda map is a map that is made in order to manipulate or exploit the person viewing the map.  Propaganda maps, which are known to have a psychological impact on the user, are often used during times of War in order to show threat or persuade whoever is viewing the map.  This propaganda map, called "Scott's Great Snake", was published by J.B. Elliot during the Civil War.
