Following the World Frisbee Championships in 1982, and with Wham-O under Kransco ownership, the world championships transformed into the U.S. Open in 1983. In 1987 the World Flying Disc Federation (WFDF) ran its first individual overall championship. Eventually the U.S. Open and WFDF championships alternated years until Covid threw some hiccups into that schedule.

Competing with the WFC, U.S. Open and WFDF championships was Tom Schot's World Disc Championships, held in Santa Cruz beginning in 1978.

This gallery captures those World Championship events through their published documents. It includes everything from invitations to attend, to programs, results, daily updates, even parking passes.

Discs for these events can be found in the Tournaments / World Championships area, posters can be found in the Print / Posters gallery, and other related items can be found throughout the Miscellaneous area.
