Interesting original vintage air-route map of the world, showing the air distances between the important cities of the world.
The map, showing a new era in world transportation, the "air age," maps the world on an Azimuthal Equidistant Polar Projection. This allows the viewer to understand how easily the world can be connected over the poles.
The map has been dated by institutions to the years following the conclusion of World War 2 (1948 and 1953). However, the political divisions shown on the map are distinctly pre-war. The Danzig Corridor exists, Japan holds Korea and Taiwan and Manchukuo still exists, and the Soviet Union has not advanced westwards into the Baltic nations, etc. This suggests that the map was published in the late 1930s, which is early for such a map.
This edition of the map was used to advertise the South Orange Storage Corporation, based in South Orange, New Jersey.
