Betty Grable was an actress and pin-up girl, back when that was a thing. Her and her luscious legs invaded movie screens during her heyday which spanned many decades. She was in 42 movies between the 1930s and 1940s. That's almost as many movies as Dwayne The Rock Johnson has been in all of 2018. Seriously, that guy is in A LOT of movies. The key to being a good pin-up girl/actress is a good set of legs. Betty Grable had them and protected them well with a nice insurance policy.
Nowadays we don't talk about pin-up models outside of locker rooms. That would be great if pin-up models became household names again. And no, I'm not just saying that because my dream has always been to be a pin-up model. I'm just saying it would be cool...
