Hot on the heels of my last post, I received a scan of a contest card reverse from friend o' the Archive Mike Tavenner. You will see the "A" identifier also is on the back of the card.
He also sent a long a front scan, which differs from the Nov. 25 version I showed last time around and prominently features our ol' buddy Bazooka Joe:
Next on the hit parade, are there similar variations for each type and date?
Mike also confirmed there is no "C" version of the Nov. 25th card known in the hobby
I doubt if you could identify them now but I wonder if any of the contest prizes have survived the last 54 years?
