These are genuine Bicycle brand playing cards made in the USA by the United States Playing Card Company from their original plates. They are authentic reproductions of their well known "International Aircraft Silhouette Spotter Cards," originally produced for the United States military in 1942. The box includes an instruction card, two jokers, and is sealed and cellophane wrapped.
These cards feature silhouette images of Allied and Axis aircraft in use during WWII and were designed to be entertaining as well as educational. The images depict a front, side, and bottom silhouette of the aircraft, the view ground observers would be most likely to see.
