This is a highly intriguing and informative map that delineates the numerous network of communication cables connecting the world during the time of printing, 1939. Several keys, and descriptive notes are provided as they are absolutely necessary to fully understand the map and smaller inset maps.
Colors represent ownership of the various cables by country as well as their stance in the ongoing WWII with regards to the strength of their commitment to the Allied nations or Germany. Many countries at this time are colored blue to represent their neutral position. Much of this would change as the war pressed on. Another detail worth noting is the solid or dashed circles placed around major cities that identify censorship as either direct or indirect, an important variable during times of war between multiple nations.
Two smaller maps include the "Communications in the Pacific," and the "World from a German Broadcaster's Switchboard." The projection employed in the making of this map is noted within as "azimuthal-equidistant." In short, it describes a map that the distances from all points are at proportionally correct from a center point.
Condition: This map is in A condition, printed on two separate sheets that have been professionally joined. Some light toning appears at the top and bottom of the map.
