The Adventures of the Sea Hound was a fifteen minute radio program featuring the proud Americans Captain Silver and his sidekick Jerry. From 1942 to 1944, the broadcast was produced in conjunction with Nelson Rockefeller’s Office of Inter-American Affairs. One objective of this department was to ensure North and South America were united in the war against the Axis forces. Each Monday, Nazi-chasing hijinks took place in a new Latin American country. To educate young listeners about the various locations, this map was published to be used in conjunction with the radio program.

Resources and exports are depicted pictorially, and the border of the image shows the flags and leaders of each country. A key at the bottom of the map shows “Products Vital to the War Effort of the United Nations,” establishing a concrete link between the products of South America and success on the front. An interesting piece of wartime propaganda aimed at a young audience.
