Bravo, guys, bravo!!!!!!!!!!! I am so proud of you.
As I wrote in NEVER CHEAPER BY THE DOZEN, the set was released right after the 1960 baseball season. With NFL football in full swing, it would make sense that if six small /four large boxes fit best on their printing press, selecting a football player to be on both sizes would ostensibly make sense. Johnny Unitas was the game face star, but Gif played for New York, and the General Foods' corporate offices were in White Plains, NY, so Frank would have been chosen over Johnny U. The New York market towers over Baltimore. I KNOW this is pure speculation, but I hope you give it some consideration.
Foremost, would any of you gentleman confirm or enlighten me about the brief, specific window of time during 1960 when these Post Cereal Sports Stars appeared on their Grape Nuts Flakes boxes?
Again, kudos to youse guys for your tenacity at joining forces on the Net to present the hobby with some new information.
Best regards to you all.
