From the logo at the bottom right on the back, my guess is these are from 1996. Simple design. The back is interesting, as it breaks out the players stats by ball park. Check it out.
So thanks James for a great oddball set that's pretty basic in look, but 30 well appreciated cards. Look up James on The Bench and strike up a trade with him. He did include one other card, but that is for a future post.
