Proof said, why no Gail Davis? Well, because Gail Davis was not in Annie Get Your Gun (which is a musical). No dis intend to Ms. Davis, she was a great Annie Oakley. So here is a post just for her.
It might be Alice Van on the rearing Palamino above, but maybe not. Gene Autry called Gail a "perfect western actress" and she participated in rodeos and often did her own stunts.
Proof Positive: Vintage Babe of the Week: Annette Andre
Smitty/Darleen: Friday Fiction (although Annie Oakley was the real deal)
