Ashland Oil ran a contest at their gas stations in 1967 called Grand Slam Baseball. You received a game piece when you visited the station and prizes included cash, World Series tickets and a bicycle for kids.
There were 12 different players in the set and the only Oriole was Frank Robinson. There aren't a ton of big names in the set, but it did include Al Kaline, Harmon Killebrew and Joe Torre. Jim Maloney is the toughest, since he was short printed. Others included in the set were Jim Bunning, Elston Howard, Ed Kranepool, Bill Mazeroski, Ron Santo, Leon Wagner and Pete Ward.
