I've got 20,690 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: 1960 Fleer #29 Gabby Hartnett There are ten Cubs cards in the set and this is the only one with a horizontal orientation.
1990s: 1991 Fleer Traded #79 Chuck McElroy The yellow borders probably look great on Pittsburgh Pirates cards. Cubs cards, though, no so much.2000s: 2005 Team Heroes #69 Corey Patterson The three-in-a-row Fleer streak gets broken by a card from Donruss.
