Amazing Adventures #12

This May 1972 Marvel issue puts the Beast front and center in one of the era's most arresting cover images — penciled by Gil Kane and inked by Joe Sinnott — showing a snarling, grey-furred Beast looming over a fallen Iron Man in his classic red-and-gold armor, with the Beast's own speech bubble proclaiming "I did it! I killed Iron Man!" The tagline "One Avenger: Dead on Arrival!" makes it clear this issue isn't pulling any punches. With a story titled "Iron Man: D.O.A." and a creative team including writer Steve Englehart and artist Tom Sutton, this is the kind of attention-grabbing single issue that reminded 1972 readers exactly why they loved Marvel.
