And as many times before I received an addition, a piece of the puzzle, that I've obviously overlooked, by faithful reader Hannelore from Austria. Not identical but possibly related ?
(26-06-1907 – 1981 Hamburg)
Hilde is mentioned in: "Der neue Rump, Lexicon der bildenden Künstler Hamburgs".
This is the only example I was able to find and I doubt the auction catalogue title: "Maxe Kirschberg". It is obviously a Jewish older man and dated 1940.
As always: all information welcomed !
