By 1940, America had seen much of Europe and the Far East become enmeshed in what would be called World War II, as fascist armies invaded several nations, bombing and razing dozens of populous cities. Knowing that we would inevitably become involved, the public started becoming more conscious about making sure our own homeland would be well defended if and when the time came. This card series marketed to the kiddies who were themselves caught up in the enthusiasm.
The card fronts show a piece of color artwork depicting a military or civilian group of people taking steps to protect our nation; the card title sat at the bottom of the image, which was surrounded by a red, white, and blue border. At the top of the image sat the card series logo, a shield featuring the series title.
The card backs featured the card number at the top, followed by the card title and a large block of text explaining the image. Below this advertising the rest of the set and giving copyright information. The card text has been found in both blue and black ink.
The American Card Catalog reference number is R50.
