A PSA graded GEM MINT 10 - 1977 MSA Baseball Disc of Hall of Famer Steve Carlton of the Philadelphia Phillies featuring the Holiday Inn Hotels ad on the back. 

From 1976-1983, Michael Schechter and Associates (MSA) of New York issued several different disc sets that were licensed by the Major League Baseball Players Association with the team logos removed from the player's caps. Some of the discs feature four stars above the photo of player, while others feature a different company name above the photo of the player. These discs can be found with blank backs or with advertising on the backs for companies like Crane Potato Chips, Holiday Inn, Pepsi-Cola, Wiffle Ball and a variety of restaurants and snack shops. Some discs can even be found with an offer on the back for companies to purchase discs directly from MSA to be used as promotional items.
