So I just stumbled upon this image of Clara Bow over at The Sunset Sessions tumblr, and it made me pretty happy. Surfing and cowgirls combined? Come on!
So obviously I got obsessed with this, and although I didn't find out much specific information about this image, I did find a few others that are clearly form the same shoot.
This one above is my favourite.She looks so happy.
Also, here is a bonus 1929 artwork of Clara Bow surfing, by Enoch Bolles.
