The Avair was the second disc made with a beveled edge. The Eagle / Aero was first molded in 1983 the Aviar in 1984. This Avair is very rare and in great condition. This early version has very small letters that say "INNOVA CHAMPION DISCS, INC." on one side of the underside of the disc and on the other side it says in even small raised letters "PATENT PENDING". These discs are very unusual and difficult to find.
