Pin Up" is often associated with WWII calendar girls of the US ... I think it's important to remember that their style was ... and is ... largely universal. You can find Pin-Up style all over the world. It's not something reserved for sweet rosy cheeked gals from the Midwest. So along with all my other Rockabilly rants, I'm going to start introducing Pin-Ups from around the globe.
My first choice is Sonja Henie, from Norway.
Sonja was born in 1912, and went on to become a rather famous Norwegian figure skater and movie star. She was an Olympic Champion 3 times over, and at one point, was apparently the highest paid starlet in Hollywood!
