ESB York Peanut Butter Card Set [Canada] (Cracker Packers, 1980)
An unusual card set, in that they are ROUND. These cards were a promotion in Canada, and were packaged under the lids of peanut butter jars! There are six in the set. Here are the fronts and backs of each card!
Nice to see the 2-1B card at the end, which was an unusual choice.
