Jack Kirby did one of my favorite Iron Man covers for issue #80. Inked by Al Milgrom, I think this image was used on merchandising.
Why do I think this is such a great cover? It has no action, fighting, or drama of any kind. Shell-head even has the helmet with the nose.
I admire it because it puts the Armored Avenger in a trippy outer-space setting, something Kirby excelled at drawing. We had seen Iron Man in a couple of intergalactic fights before this, most notably during the Kree-Skrull War, when he was tearing into spaceships. Kirby brought back the vision that Tony Stark's armor could take him anywhere in the galaxy. Nuff Said!
