I came across this image which was a scan from Stephan Biesty's book "Incredible Cross Sections" that was just fun to stare at. I always like his books since he seems to cram a whole lot of action into the drawings. This is a big scan, and shows a lot of details. Take a peek at it. (click the image)
I found this on what appears to be a French web site with some old (and newer) scans of Apollo posters.
Remember this old poster from National Geographic?
