Dave HornishSpending the day surfing the web and I found a reference to a variation of some 1941 Play Ball cards. Instead of the line under SPORTS HALL OF FAME reading "Watch for other famous sports stars...." on the reverse, the variation states Also ask for Blony Super Bubble Gum...".
You can see the differences below in the scans I just stole off the web (forgive the double Klein). I never realized this. Is each card available with both backs or does this follow the Copyright/No Copyright (low series/high series) progression?
