The world maps are thumbnail summaries. They call attention to the major military and political developments of the year and include events not featured on the individual stamps. Color coded for easy identification of friend and foe, they're "a year in summary" at a glance.
The 1991 stamps spotlight the world at war in 1941, featuring Burma road, Peacetime Draft, Lend-Lease, Civil defense, Pearl Harbor, US Declaration of War, and more.
