IRON MAN #31
(Nov., 1970) "Anything ... for the Cause!"
Cover art : Marie Severin.
Script: Allyn Brodsky.
Art: Don Heck/Chic Stone.
When Stark visits his factory on the Pacific island of Lakani, he and Iron Man have to deal with a bunch of phony rabble rousers called the Smashers! Pseudo-enviro story with LAME villains, little Iron Man action and transparent plot twist. Significant only for first appearance of Kevin "Guardsman" O'Brien (yes, with an "a").
xkot's Recommendation: 2 1/2 repulsors!
