Rare German mapping of Finland, showing the country in great detail and issued for military use.
The map is marked "Nur fur den Dienstgebrauch," or only for use by the service.
Finland became a natural ally of Germany during the Second World War in 1941, when this map was printed. That year, it launched the Continuation War when it invaded the Soviet Union in retaliation for a Soviet air raid. It would initially regain territory lost in the earlier Winter War, even reaching Leningrad, before being pushed back. It would sign an armistice with the Soviets in 1944, opening the Lapland War with Germany.
