It’s about twenty-five minutes long, done with cut-out animation and soap-on-glass for a lot of the effects.

I've seen stills from it! I think I got to it via Honegger. It's based on a wordless novel, a genre I don't know enough about but have always been very interested by whenever I run into it.

Looking at the first few minutes, I suspect it was not always this fuzzy, but I have no idea if a cleaner copy exists on the internet. If it get a restoration, Flicker Alley or Kino is where I would expect it to turn up.
