Thanks Dan!
I had already started some brand new period correct nose art for the plane when the log book sketch turned up. At that point, there was only one way to go! So I started over.
I traced the sketch so the proportions would be exact and went from there. In the sketch, she was nude, and the museum was more comfortable with a swimsuit. So I designed a '40s swimsuit. All I could tell from the mess of hair in the sketch was that it was blowing behind her. So I gave her some curls and had them starting to straighten out in the wind. The bell in the sketch looked like they had found an old engraving. Rather than have that engraving, I took the opportunity to use the bell to highlight the War Bond contribution. That is the biggest digression from the sketch apart from the nudity, but I think it is ok and there is precedent for that type of recognition on other aircraft. As Chris said, the lettering is based off of other group aircraft. Whenever I work on a project like this where I have to "invent" history, it is very important to me that all elements of the art have a cohesive look to aircraft in the rest of the group/squadron. I especially can't stand post-war typography on the side of a WWII aircraft! In this case, "Liberty Run" gave me a pretty good starting off point to design the lettering.
It's a pretty exciting project, and I'm thrilled to be involved!
