MYSTERIES OF UNEXPLORED WORLDS was a great blend of science-fiction and horror comics (and even a little superhero toward the end), a hybrid – and because it appealed to fans of all, had a terrific 48-issue run (1957-1965). Many issues featured the workhorse and master Steve Ditko, along with many other great talents. Whether you want the unusual, the exciting, outer space, or the horrors of inner space, we have over 1300 pages for you in five great books – THE ONLY complete collection in print! This Book: Issues #18-26
