American Colortype Company
The American Colortype Company produced and marketed a set of 28 colored postcards showing both the U.S. Army and the U.S. Navy in various aspects of training or weaponry. The views depicted are of the World War I era but are domestic locales prior to our involvement in World War I.
Image sides have a black and white or white only text imprint centered at the bottom or along the upper right edge identifying subject matter. The reverse side has a paragraph of explanatory detail taking up the lower half of the message end of the card. Postcards are numbered on the reverse with a publisher imprint for American Colortype Co., Chicago.
