Bought a collection of 1950's, 60's & 70's cards in December & this unknown issue was in a notebook labeled "Complete 64 Card Set". I am selling these as singles & they are close to the exact size as a T206 Tobacco card. You are bidding on this knowing that I know nothing about this issue, as I have looked through a couple books & can't find any info on it. Many thanks for looking at my auction item! (The number in parenthesis at the end of the title is the date of my listing).
