Prior to 1990, discs were loosely approved by the PDGA. Many discs were grandfathered in as approved. There are no approval forms nor do the actual test discs exist today. This isolated section of the gallery serves to provide examples of discs that were either grandfathered in or actually tested with no existing records.

The goal is to provide a gallery that is complete as possible with either a sample of or the actual test discs used that were approved by the PDGA
