1981 MSA Discs
The 1981 MSA (Michael Schechter and Associates) Discs were sponsored by Peter Pan and Sunbeam Bakery although their names do not appear on the cards. Being unlicensed my MLB, all logos have been airbrushed off. According to Pete Williams, author of Card Sharks, MSA was a licensing agent of the MLBPA in the 1970s and 1980s (http://www.petewilliams.net/blog/?p=748) so they had access to the player's likeness for these promotional items. Basic information about George was included on the front while the backs are blank. The 1981 set consisted of 32 players on unnumbered discs.
