This may have been the only Iron Man comic I had as a boy, but it was a good one. Drax the Destroyer and Iron Man take on the Blood Brothers and Thanos! This story had great fight scenes, cool flashbacks and a twist ending.
I didn’t know it at the time, but this was one of two Bronze Age comics I had in my collection that would be worth something in the future. (The other was Giant-Size X-Men #1.) Of course, they were both in the box of comics I sold to a friend in the late 70’s. Now I only have a “Marvel Milestone” reprint.
