I was lying about Keedy; look what i just found!
It is so fun to remember this stuff! When it was announced that the Hawaii Islanders were moving to Colorado Springs for the 1988 season, I got out an SCD and mail ordered a 1987 Pro Set team set of the Islanders for the purposes of autographs. In my naivety I didn't even realize that they would also switch parent clubs to the Indians (I think the Islanders were the Pirates AAA team - EDIT-It was the White Sox). Still, I got Keedy and Brian Giles (the black one with a mustache, not the future Pirates star of the same name) on this set.
EDIT TO ADD-I see that Keedy only played 3 games with the Sky Sox, in 1989! I'd bet I got him in 1988 when he came through with Tucson. Ah, the memories!
Get me your address if you want this card; I'd be happy to send it out (though you may only want the '88 Topps as you mentioned).
