This is a Vintage 1978 North American Flying Disc Series - 165G 80 mold Frisbee Disc. It is in excellent condition, but does have some storage wear and slight nail delay marks. It has a blue and gold hot stamp on unpigmented plastic. This 80 mold 165 commemorated the 1978 North American Flying Disc Series of tournaments: Qualifying tournaments for the prestigious 1978 World Frisbee Disc Championships in the Rose Bowl. The annual NAS discs featured a prominent player on the hot stamp each year, and in 1978 it was competitive great, Dave Marini, doing the honors. Thanks for looking!
