Another great Hall of Famer SP, you are a collecting machine, Larry!
Progress made on the 1977 Topps Mexican Set this month in the much maligned category of CHECKLIST cards. Here's an uncut two card "strip" of Card #'s 204 & 256 (Bears) of the '77 Mexican set. I have not seen any cards from an uncut sheet in this set before, but can confirm those darn perforations ARE factory.
