Forbidden Worlds #2 (American Comics Group, September–October 1951) is a 52-page Golden Age horror anthology presenting nine stand-alone tales of the supernatural. The issue opens with "The Mists of Midnight," in which Audrey Clark encounters a fog-shrouded menace, and continues with "The League of Vampires," where Nancy Lewis faces a bat-eyed visitor commanding her toward a dark laboratory. Further stories explore a witch who prophesies Andrew Jackson's presidency, a spectral sky-ship, a magic coin, and a boy who communes with the dead — a representative showcase of ACG's early blend of horror, folklore, and proto-science fiction.

Published under ACG's imprint Preferred Publications Inc. and edited by Richard E. Hughes, Forbidden Worlds launched in 1951 as the companion title to Adventures Into the Unknown — one of the first ongoing horror comics in American publishing history. Issue #2 appeared before the 1954 Senate subcommittee hearings on comic books reshaped the industry, giving it the raw, unfiltered atmosphere of the pre-Comics Code Authority era. The cover by Ken Bald — featuring a bat-eyed monster — exemplifies the bold visual language ACG cultivated before market pressures forced a tonal shift. Interior art is by a roster of Golden Age freelancers including Lin Streeter, Charles Sultan, and King Ward.

Today Forbidden Worlds #2 stands as an authentic document of early American horror comics and is freely accessible in the US public domain. It offers collectors, scholars, and genre enthusiasts a direct window into the birth of pre-Code horror anthologies — a format that would define popular culture for the following decade. High-grade physical copies command hundreds of dollars at auction, while the full issue is available for free download via the Internet Archive.
