The Thing and Iron Man* take on the Blood Brothers! This was a nice heavy weight brawl, with some humor thrown in at the beginning and end. (This fits in near the middle of the Thanos War saga, where Thanos uses the Cosmic Cube to try to take over the universe. I had a few issues of Captain Marvel and the Avengers to go along with this comic, but as an 8-year old, I didn’t really have the patience for multi-issue epics. Later, I bought the TPB that collected them all nicely.) This was the last issue of “Marvel Feature” which became “Marvel Two-In-One” starring the Thing.
*This is a rematch from Iron Man #55 which started the whole Thanos trouble.
