Great maps communicate something about the era in which they are published. This US map, first published in National Geographic in December of 1940, is a cartographic gem. This map included two insets that tell much about the time it was published. One inset shows the population shift between 1930 and 1940, following the devastation of the droughts of the 1930s. Another inset shows the Army Service Command Areas and Naval Districts as the US prepared to enter WWII. Any map collector will delight in the balance between features and extraordinary detail. The 1940 United States map features: • Thousands of cities and towns, classified by their population • Road network easily identified against the light background • Mountain ranges with beautiful relief shading • Waterways, national parks, and national monuments • Inset showing the population of all 48 states, and the gain or loss between 1930 and 1940 • Inset showing the Army Service Command Areas and Naval Districts across the US • Excellent detail in northern Mexico and southern Canada
