1941 Hammond Pictorial Map of United States Defense Mobilization pre WWII

This is a c. 1941 C. S. Hammond and Company pictorial map of the United States highlighting the military and economic resources available on the brink of World War II. Blue-colored cogs highlight industrial areas around the country to illustrate the manufacturing might that could be brought to bear. Other defense industries are marked on the map by icons, including shipyards, factories for making planes, airplane engines, munitions, tanks, guns, steel, and aluminum. Army and navy bases are identified as well, as are army and navy airfields.

The Pictorial Border - A Show of Military Force

It is the pictorial border, however, that immediately draws the viewer's attention. The air, land, and sea forces of the United States military are put on full display, creating a forceful image that undoubtedly counts as propaganda and shouts 'support the military'. Cutting edge aircraft, such as the Boeing B-17 Flying Fortress, Consolidated B-24 Liberator, Lockheed P-38 Lightning, Grumman F4F Wildcat, and Curtiss P-40 Warhawk, are prominently illustrated along the map's top border. Tanks, artillery guns, howitzers, and supply trucks along the map's two sides represent ground forces.

The Navy

Perhaps the most incredible part of this piece (with the benefit of hindsight of course) is the placement of the battleship front and center along the bottom border. The legendary naval engagements fought between the United States and Japan had not yet occurred, and naval strategists believed that the battleship, not the aircraft carrier, would be the key element to success on the world's oceans. An aircraft carrier appears to the right of the battleship, complete with its aircraft on the flight deck. A heavy cruiser steams to the battleship's left, surrounded by torpedo boats, light cruisers, destroyers, and submarines.

Insignia

Illustrations of American Army and Navy insignia frame the entire piece, with army insignia on the left and navy insignia on the right. Army insignia of rank, from general to private first class, are situated at the top left, while insignia of 'arms and services', such as the infantry, ordnance department, signal corps, and medical corps, are on the bottom left. Naval insignia of rank are just opposite, on the top right, while naval specialty marks, such as sharpshooter, bugler, machinist's mate, and cook, are on the bottom right. A sample of Army and Navy Air Corps insignia are included along the top, while the insignia of army headquarters, field armies, army corps, and army divisions are along the bottom.
