Neonbible, my avatar comes from a 1975 cover painting for Analog Science Fiction magazine.
It's been speculated that the artwork created for a short story in that issue influenced the design of Chewbacca and Wookiees in general.

I saw the original piece in a Science Fiction art book back in the 80's, and it only took me eighteen years to find out where it was originally from! ;)
I suspect I saw this cover in the 70's at some point. It certainly got into my subconscious somehow!
And to steer things back on topic, according to DVD Savant, a complete Metropolis print may have been found!

I admit I've not heard of a 9.5 mm film format before! Some forgotten competitor to 8mm?
