During the days following the Japanese attack on Pearl Harbor a group of American pilots who had volunteered to fight for China, before America entered the war, fought their first combat.
The American Volunteer Group's success against the Japanese soon earned them the sobriquet, "Flying Tigers." What eventually became the Group's emblem was designed by The Walt Disney Studio, and featured a winged tiger flying out from a blue V for Victory.
This metal lapel pin is a recreation of that emblem.
