I was surprised to see (in an issue of Archie's Funhouse) a story illustrated by Kurt Schaffenberger. Schaffenberger was best known as the artist on various Silver Age and Bronze Age Superman related titles like LOIS LANE, and later drew both JIMMY OLSEN and SUPERGIRL when those three titles merged into the giant-sized SUPERMAN FAMILY comic book. He also drew the Captain Marvel Family in SHAZAM! in the late 1970s.
As soon as I looked at the first page, I was struck at the familiarity of the poses and immediately checked the credits. Of course...! Schaffenberger. He was so perfectly suited to drawing for Archie Comics, too -- I immediately wondered why I hadn't seen more Archie stories drawn by him. The story in question seemed to be from the very early 1970s, with all the characters wearing bell-bottoms and talking about "the new generation" and "peace & love" (the plot of this particular story being to get Moose to give up his violent ways as hearkening back to the "old generation's" way of thinking).
I'm guessing Schaffenberger was still getting plenty of work at DC at the time (so if they were treating him well, and it paid better, then why should he leave for a lower page rate at ACP?) Still, there came a time 15 years later or so, when his work wasn't in such great demand at DC, so I wonder if he ever returned to ACP in the mid-1980s or later? This was the case for people like Chic Stone and Gene Colan and Joe Staton, and a few others who escape my mind at the moment -- when newer, younger "hotter" artists displaced them on titles at Marvel and DC, they went to ACP and found work.
But as I mentioned, Kurt Shaffenberger's style needed only slight modification to fit in perfectly with the ACP house style. He could have been one of the GREAT Archie artists if he had done more work, since he was well known for his pretty girls (that's why he was the regular artist on LOIS LANE in the first place).
Another DC artist whose work I've never seen at ACP, but who strikes me as someone who'd have been a perfect fit at the company, is Ramona Fradon. She was known at DC primarily for her pencilling work on AQUAMAN, METAMORPHO, PLASTIC MAN, and SUPER FRIENDS, and as the artist on the long-running BRENDA STARR, REPORTER newspaper strip.
