Here is an oldie but a goody from 1981 Topps. As you can see, these cards are big, roughly about four times the size of your standard issue baseball card. I have three of them including this Nolan Ryan card, it is one of six Houston Astros cards, the other Astros in this set are Cesar Cedeno, Jose Cruz, Art Howe, Terry Puhl and Don Sutton.
I also have the Texas Rangers' Al Oliver and Buddy Bell cards, the others in that set are Jon Matlack, Mickey Rivers, Jim Sundberg and Bump Wills.
Back then you could order these cards in 18 card team sets for $5, available for these teams, Yankees/Mets, Dodgers/Angels, Rangers/Astros(12 cards), Cubs/White Sox. The Reds, Phillies and Red Sox were in 12 card sets each. I don't know what players were in those sets, but it would have been nice to be able to have them all. Just a quick trip down memory lane in 1981.
