When I came across this set, the paperwork that came with it told the whole story. In 1984, Buick was the exclusive automotive sponsor of the Summer Olympic Games in Los Angeles, and to mark the occasion Buick designed this limited edition commemorative pin set, "Buick and the Olympic Years."
There are seventeen pins, each depicting an automobile commemorating an Olympic Year and a popular Buick model produced that year. To complete the set, Buick's Olympic sponsorship pins for both the 1984 Summer Games and the 1984 U.S. Olympic Team are included. Each pin was hand-fashioned by an artisan in crystalline enamel with gold plating. My set is No. 124, and here is the original document that came with it:
