Sorry it took so long to respond, I was taking pics then had to upload them to my server.
I use to buy and sell cards for a living. I got this sheet thru a mail in offer. The cards to mail in were seriously rare to find. Its not a crappy cereal thing LOL Its from Skybox. Its from the early 90s and havnt seen these on ebay or anywhere else. I was gonna look at Beckett but they want money LOL So I didnt get no info there.

As for the sports card stores not knowing anything... I think its just the area I live in. I'm in Alaska and not to many ppl up here to go to for info.

Well here is the URL for a few pics.
