I have never seen any of the above cards, but if the '96 Aficionado First Pitch Preview does exist, then I think I know who has one. There was a collector named Rich who used the ebay id donyboy23, and he amassed a truly enormous collection of samples, promos, and previews in the late 1990's and early 2000's. He hasn't bought or sold anything on ebay in a couple years, but his About Me page shows a First Pitch Preview #99 on his "Have" list. I tend to believe him because I remember he offered some huge $$$ for First Pitch Preview cards on the Usenet message boards during that time. I have tried to contact him a couple times in the last year or so, but I've never gotten a response.

Another card that I would like to see is the '99 SP Signature Autographs Gold NO AU. Who has seen that one?
