OK, just to correct something I said here, I have just now seen on eBay a 1993 Honolulu Sharks card of "Ben Agbayani". So that's now four cards that I've ever seen from these theoretical 1993 Hawaiian Winter League team sets.
The card has a gold autograph on it but I don't know if it's a facsimile autograph or a real autograph. So I don't know if the card was some sort of insert in the set or if it was autographed after the fact.
I'm not any less suspicious just because there's another card. As I said before, "caveat emptor".
