Bobski,
I've been meaning to ask about that, and similar avatars that a few folks have. I have a WWII booklet, perhaps 3X5 in size, that details allied and axis aircraft from the war, or, just after. It was given to me by a classmate in 4th grade, and it was old even at that point, perhaps 45 years ago. The photos in it are similar to your avatar and a few others I have seen. The book seems to have been aimed at kids, and has descriptions of how air power is utilized in wartime, at least circa 1945, or so.
The condition of my book is poor. It is missing the front and back covers, and has been scribbled in by some kid who isn't a kid anymore. Did your photo come from a similar book?
Best,
Ted
