This is the third and last volume covering Marvel's super-hero comics of the 1950's. This one reprints Sub-Mariner #33 to 42. This ten issue run makes it much more successful than the revivals of The Human Torch and Captain America, which lasted just three issues each. Why was Namor more successful than his rivals? Well, according to the introduction by Roy Thomas, Marvel was negotiating with a Hollywood producer for a Sub-Mariner television series, due to the success of the Superman show. Of course, if there was no Sub-Mariner comic book being published, that would make the property less attractive to Hollywood. So, the comic stuck around until the TV deal was dead in the water (so to speak). As for the quality of the comics, they are above average for the time period. While the stories aren't as sophisticated as today's readers are used to, the art by Sub-Mariner creator Bill Everett is great. This is the best of the three Atlas Era Heroes book.
