I have spent hours and hours trying to research who created this lovely etching of an old man writing (attached). I am hoping that someone might recognize the style and know the artist. Any help would be greatly appreciated.

Hi
Don't have an answer(yet) but I wanted to be sure you saw the "signature" at the top of the work. It runs vertically, apparently top to bottom at the right of the head. Perhaps someone will recognize it, knowing where to look.

Hi... The artist is MINTZ, HARRY (Born 1907 American) .
See the signature- mintz - at the link:
