Another artist I knew from the 1970's that I had no idea went back to the early 40's is Art Saaf.
I knew him as the guy who drew Supergirl in the early 70's
ADVENTURE COMICS issues.
And then in her own 10-issue
SUPERGIRL series in 1972-1974. I'm surprised how much issue 1 is selling for! These were fun but unspectacular issues. I enjoyed them as much for the Zatanna backups as for the Saaf lead stories.
When I was reading early 1940's issues of PLANET COMICS, I saw features with Saaf art, and some particularly nice good girl art. He was a peer of Murphy Anderson on the Fiction House titles.
