Here are some pictures of a baseball I came into possession of. When you find a signed baseball from the 1980s, you pretty much always expect it to be the ’86 World Series team, especially when the first two names that jump out at you are Rafael Santana and Wally Backman.
But then I saw Kevin McReynolds who didn’t arrive until 1987. Santana departed after the 1987 season, so that was the only year they played together and therefore the only year the ball can be from. So there it is, a New York Mets team signed baseball from 1987.
And yes, this baseball was apparently purchased at Sea World.
