Dr. Doom fights Captain America!

I was going through some of my old comic longboxes and found this fantastic comic from 1977. I remember picking up this copy of Super-Villain Team-Up at a yard sale or something quite a few years later. I was really drawn to the beautiful Gil Kane cover- just look at that Red Skull! Plus the story was by the under-rated Bill Mantlo, my favorite writer when I was growing up for his work on The Micronauts.
