When superhero comics went out of fashion in the postwar era, Moldoff became an early pioneer in horror comics, packaging two such ready-to-prints titles in 1948. He recalled in 2000 that, "I had shown "This Magazine Is Haunted" and "Tales of the Supernatural" to [Fawcett Comics'] Will Lieberson before I showed them to [EC Comics'] Bill Gaines, because I trusted Will Lieberson much more. He showed it to the big guys at Fawcett, and he said, 'Shelly, Fawcett doesn't want to get into horror now; they don't want to touch that'".
