And the only non-photographic clue I have, a word (location?) handwritten on the sheet holding these negatives. (3/2, I can't count today)
I'm assuming German because the book of negatives is printed in German (and I was told years ago that it was from Germany), and a photographer not only because it's a book specifically for holding negatives, but the film shows every sign of being self-developed. Also, a lot of the shots seem to be a range of exposures for the same subject.
I'll cross-post these to Bluesky later ... I've a whole book of negatives to go through :)
