Douglas Campbell, Ace Obverse

The first American-trained pilot, flying with an American unit to achieve the status of ace, Douglas Campbell (1896–1990) shot down six enemy planes by the end of the war. He flew with the 94th Aero Squadron, the famed Hat in the Ring gang that included the top US ace, Eddie Rickenbacker.
