I believe the artist who did three pieces for Madhouse,
and as far as I can see nothing else for Archie, is Don Orehek. His
style changes somewhat across the years at the B&W humor
magazines like Cracked
(the page here is from its
#35, April/64), but I tell myself I see resemblances. The Madhouse
page is from the #10 "Double Take." The first tier, at least,
could be a Shut-Up at Cracked.
Or this may be someone whose name we'll never know.
