So, I'm working on reproducing the chick with bike artwork, and am slowed down by the loss of detail on the woman's face. I can wing it and get a close approximation, but am keen to be as accurate as possible on this.
It occurs to me her outfit is that of an old timey female aviator. An Amelia Earhart type. Checkout this picture
. And this one
(of Ruth Elder). Those outfits are very close!
I'm thinking now the bike is an original drawing, and the woman is an old historical photograph or something along those lines. I've dug through Google Images using various keywords, but haven't found the exact image yet. It's possible it isn't even a photograph, but an old drawing.
Anyway, thought that was neat.
