IRON MAN #92, 1976. Inked by Al Milgrom. I like this one, with Kirby drawing the original armour one more time, and a nice general silver age look to the layout.
AVENGERS, THE #154, 1976. Milgrom again. I like Attuma, he's one of the better minor villains of the 1960s books, although the disembodied talking heads of the Avengers are a little creepy.
INVADERS, THE #33, 1978. Dave Cockrum inks, which I think is one of the few, if not only, time we saw that combination. Cockrum is, to my mind, one of the best of the mainstream artists to come out of the 1970s, so that's nice to see.
