This collection is all fastback Frisbee related. Made by Wham-O the original
fastback was one of the easiest to throw recreational discs made. It became the
standard for events like maximum time aloft and thrown run and catch, but the
primary use has become for Frisbee or K-9 Disc recreation and competition. Many
models and manufacturers now exist. These are some of the originals.
The American Flying Disc Open is one of the first major overall tournaments.
For a few years they listed the previous distance winner on the next year's fastback.
Distance as I recall had to be thrown with a fastback.
