Fascinating WWII broadside propaganda map, published in India, in order to keep the local populous informed about the War.
The map shows the theater of war for the Russo-Finnish War (also called the Winter War), as well as the course of railways, roads, and tracks. While the Winter War was not strictly part of World War II, it was one of a series of conflicts that involved the same parties and were closely related to what would become World War II.
We have been unable to discern who the C.P.D. were, but we do know that they were located somewhere in India, and were responsible for this W.N.R. series of World War II propaganda maps, published from circa 1943 to the end of the war.
