I found a woodcut by Elsa Haensgen-Dingkuhn (1898-1991)…
Elsa Haensgen-Dingkuhn was a graphic artist and painter from Hamburg. The depiction of children became one of her central themes from the mid-1920s onwards with the birth of her own children. Her descendants run their own website with a selection of her works.
In the “Handbuch des Kunstmarktes: Kunstadressbuch für das Deutsche Reich, Danzig und Deutsch-Österreich”, published in 1926 by Antiqua Verlags-Gesellschaft Kalkoff, Berlin, she is mentioned on the same page (195) as Wilma Bräuner.
The signature is a good opportunity to point out the dangers of paper silverfish, which have presumably nibbled away parts of the signature here…
