So why on earth would I get a card of a guy that made one career appearance with the Cubs, just one inning in 1970?
My last name is Kosman. There has never been an official baseball card of anyone with that name. Jerry Koosman and Jim Cosman are as close as as anyone has come. Koosman was a Met and Cosman a Cub. That makes it pretty easy for me.
When I saw the card with a price of less than ten bucks, I went for it. Is it a real signature? I hope so. I also figured that there isn't much of a reason to make a forgery of his card.
