Did you look at p. 386, caption:

"Striking photograph of rocket scene from German Film 'The Woman in the Moon' [...]"

Who wrote all over that issue? Looked like someone was really into writing in the margins -- names, addresses, manufacturers. I wonder why. Seems like there was a lot of look-ups done. I can't even fgure out how you'd do that then -- maybe in a library with all the major cities phone books? That's work!

Or was this part of the production product of Popular Mechanics, a step done by collecting notes from the reporters, maybe to archive?
