I have taken on the task about 10 years ago to get cards from the 1987 Topps Baseball set and update set signed. Currently I have around 450 of the 924 cards minus the 7 checklist cards and the Roberto Clemente turn back the clock card that leaves a WHOPPING 918 cards. So i'm just about half way there. Please let me know if you have any and what you are looking for in trade. I have a TON of autographed stuff so I might have what you are looking for.
Thanks!
