I've got 20,695 Cubs cards from 304 different brands listed on a spreadsheet. A random number generator picked five cards, one each from the past several decades.
1900s - 1970s: 1952 Topps #401 Bob Schultz Mrs. WW's maiden name is Schultz. I'd like to tell you that this guy is related to her, but no, he is no more her relative than Sergeant Schultz.
1980s: 1984 Donruss All-Star #42 Ryne Sandberg Notice how Donruss still has Ryno listed as a third baseman, even though he spent the entire 1983 season at second. Oops!
1990s: 1998 Metal #152 Mickey Morandini It is hard to tell from the scan, but yes, this is a Cubs card. The Cubs picked up Morandini from the Phillies before the 1998 season and he had a pretty good year for the Cubs, replacing the second-time retired Ryne Sandberg.2000s: 2003 Fleer Tradition Glossy #72 Billy Williams This card could be a what if card, as Billy could have had a card in the 1963 Fleer set that this design is borrowed from.
