WYATT EARP #22, 1959. Kirby only did a handful of covers for this book, this one is attributed to Christopher Rule inks.
TALES TO ASTONISH #53, 1964. Okay, I’m going to hope that Kirby didn’t have anything to do with designing the Porcupine, and just worked with what he was given. That’s just a sad looking character. Good pose for Giant-Man, though. Brodsky inks.
MARVEL TWO-IN-ONE #20, 1976. Inked by Frank Giacoia. I dunno why, but U-Man as drawn by Kirby kind of cracks me up.
