These Minis were made by Action-Line USA in 1978 for LMDC, the US Air Force Leadership and Management Development Center, and the Air Force Assistance Fund annual charity fundraiser. They are 3" diameter flat vinyl discs in black, yellow, and orange with "flight rings" on the outer portion of the top. "Action-Line USA" is embossed on the outer edge. Each has the same gold hotstamp for the event labeled, "Frisbee Fling."
Action-Line USA marketed the same discs as Nashville record album coasters during the 1970s.
