The 1990s provides a slew of possibilities. There are many sets with just 20-30 cards and only one or two Cubs in them. I've been hunting down over 20 of these sets and the cards are starting to arrive.
Up today are the Cubs from the 1992 Diet Pepsi set. As with many of these 90's sets, the Diet Pepsi set has a license from the players association but not MLB. That means no logos.
The Diet Pepsi set was issued only in Canada, giving us bilingual cards. There are 30 cards, but just one Cub.
It's a pretty nice action shot of Ryno going after a ball up the middle.
And that's it... the one Cub from the one year of Diet Pepsi cards.
