Panel from "The Origin of Sore, Son of Shmodin" in Not Brand Echh #3 (October 1967), script by Stan Lee, pencils by Jack Kirby, inks by Frank Giacoia, letters by Artie Simek
As Chris humbly suggests, that might actually be Magnificent Marie Severin chipping in on the background characters there, as she's definitely the doyenne of drollery when it comes to Not Brand Ecch caricature! But until definitely proven otherwise, let's declare this a Kirby JJJ and of course, there must be feasting and celebration! Let us party with pizza!
(What? You bring the pizza, I'm runnin' the blog here.)
