Cover to IRON MAN #134 by Bob Layton
Splash page from the Iron Man story in TALES OF SUSPENSE #70 by Don Heck and Mike Esposito.
You can see that there had been a different caption there where the blurb about Iron Man vs Titanium Man now is, and the caption under the credits had been different as well. It looks as though the line What More Need We Say may have originally been part of what was under the credits.
The cover to IRON MAN #55 by Jim Starlin and Joe Sinnott. First appearance of Thanos, and also Drax the Destroyer.
