   That's a very nice article, but I am confused about one thing.  In the article, you wrote:  "In 1935, Nat’l Chicle put out cards 1-84. Cards 1-72 utilized green letters on the reverse but there were two versions of the remaining 12 cards."  What are the "two versions" you were referring to?  Thanks.
