Michael Schecter & Associate handled the licensing of these cards for the MLBPA. They were issued as promotional pieces or various companies and organizations with little or no variation to the front, and completely different backs for each organization. There were even blank backs issued. This lot includes discs for Dairy Isle, Holiday Inn, Isaly's/Sweet William, Wendy's, and Zip'z. Wendy's was a much smaller chain in 1977, and their discs are one of the more difficult to obtain.
