That's a pretty hefty cost for each figure with everything considered by the time it's available to us, and I definitely understand the need to choose carefully since your subjects really are unique.
I always try to catch Busters movies when they are on the old movie channel, he was so unique. I really love him in The General.
When I started writing John Wayne, I started wondering if there would be licensing costs and kind of figured there would be as his likeness is on a lot of things yet.
Roscoe was definitely unique for the 30s and his last racer and Gilmore are in the Smithsonian. A lot of the other race pilots are neat, but probably wouldn't be recognized by most, face or name. I don't own the copyright, but I do have a bunch of photos of Roscoe and my computer, if you would ever decide to do him, or him with Gilmore, I could send you the photos I have.
