Annie Oakley.
OK so she performed gun shows well into old age and looked pretty ragged at the end there as you'd expect from someone who was old when most of our grandparents were in diapers. But when she was a young hot fox with that grace, aim, and steadiness about her...She moved well and thats sexy.
And I was flipping through this photojournalism book and found a picture of this woman dancing with WW2 GI's. And this girl is just the most beautiful lady I think I've ever seen. Just some nameless pretty woman doing what she thought was her duty, entertaining the boys before they go off and war. She's got this beautiful graceful yet unplugged expression on a face that looks designed for a goddess. You could flip through all the era's of mankind and not end up with a woman as beautiful as she looked.
Can't really think of a famous face today that I'd say was comparable. I'm trying though.
