If at first you don't succeed in identifying an artist on a comic book, keep on looking at other comics, and maybe when you go back to that first one you'll have run across some clue and a light bulb will go on.

Secret Hearts 121 (July/67) with a tier from Carl Pfeufer's known work on
Super Green Beret 1 (June/67) at Milson.
Who was expecting Carl Pfeufer at Dell, 1970? He drew all the stories in the two issues of
The Courtship of Eddie's Father; D. J. Arneson wrote them.
