Vintage 1980 ARCO Los Angeles Olympic Games of 1984 Sponsorship Enamel Pin

My father was an ARCO executive in the L.A. area and was given lots of these pins to hand out in anticipation of the 1984 Los Angeles Olympic Games. The Copywrite on the back says 1980. Great Pre-owned condition. This pin has the Olympic rings and red, white & blue stars enameled on gold-tone metal.
