Gene Tunney opinion
 

They look okay to me but I was a little concerned about the second loop on the G. I figured I'd get other opinions before I send them off for authentication or sell them. The index cards have a date stamp on the back from 1954 if that helps. It appears that was the date the original collector sent a large batch of them out to different sports celebrities. I have a Rube Marquard with the same stamp.
