The Most Obscure Carded Baseball Player in History

[frankbmd]

Take any set of baseball cards and it is fairly easy to find an obscure fellow or two with a lackluster career that you have never heard of.

Type card collectors will search for a card from an obscure set for their collection, even if the player is not that obscure or unique to that set.

Put both of these ingredients in a bowl and stir gently and what do you have?

A recipe for the most obscure, but carded baseball player in the history of the game.

But who is it?

Ideally the player should be issued in one set of cards only. The player should have a mediocre career. The card set in which he is included should be very difficult to find and if for any reason that player is a "short print" for any reason, all the better. Any evidence you can provide about Mr. Obscurity and his obscure baseball card to support your nomination will be helpful.

As your friendly thread host and referee, I am not going to nominate anyone (and in fact I do not even have anyone in mind). Scarcity is one thing, rarity is another, but who can claim the title for obscurity in the cards and on the diamond?
