About this Issue

Adventures into the Unknown #1 (Fall 1948) holds a singular place in comics history as the first issue of what is broadly recognized as the medium's first ongoing horror-comics anthology series — arriving several months before other publishers moved seriously into the genre, and well over a year before EC Comics launched its celebrated horror line. By committing to an all-horror anthology format at a time when newsstand comics were still dominated by superheroes and funny animals, ACG and editor Richard E. Hughes established a template — rotating supernatural short stories, a recurring haunt-of-the-month structure, and gothic literary adaptation — that would define the pre-Code horror genre for the next decade. The issue's storytelling range, from werewolf pulp to a comics-adapted Horace Walpole novel, signaled that horror comics could draw on literary tradition as well as lurid invention. The series that began here survived the 1954 Senate subcommittee hearings and the restrictive Comics Code Authority that destroyed many rivals, running all the way to August 1967.

In "The Werewolf Stalks," a series of terrifying accidents—train wrecks, stranglings, cars hurled from cliffs—has the countryside on edge, hinting at something beyond human hands. When Malevo, Satan’s first lieutenant, awakens to seek a queen, his ancient presence stirs fear in the shadows. Written by Frank Belknap Long and illustrated by Fred Guardineer, with a cover by Ed Moritz, this 1948 tale blends dread and mystery in a classic early horror adventure.

John WilderPierreJacquesBarbara WilderMonahan

When zoological importer John Wilder captures what he believes is an enormous timber wolf in the frozen Canadian north, he has no idea the beast is actually Jacques, a logger cursed with a werewolf's curse—and the creature is determined to reach those who caged it. As the monster escapes captivity and stalks through the night with lethal purpose, John and his wife Barbara must confront the terrifying truth that ancient folklore might hold the key to survival. "The Werewolf Stalks" is a pulse-pounding tale of supernatural vengeance where civilization's certainties crumble against the primal horror of the undead.

History

ACG grew out of the Sangor Shop, a New York packaging studio founded by Benjamin W. Sangor that had been supplying ready-made comics content to other publishers since the late 1930s. By 1943 Sangor had formed American Comics Group as his own publishing arm, with Harry Donenfeld — the DC Comics financier — helping capitalize the venture and providing newsstand distribution through Independent News Company. When Fred Iger bought into the business in 1948, ACG launched Adventures into the Unknown under the B&I Publishing imprint, with Richard E. Hughes as editor; Hughes had been working alongside Sangor since the mid-1930s and would remain the title's guiding editorial hand for its entire nineteen-year run. The debut issue drew on pulp-fiction talent, with most of the scripts attributed to Frank Belknap Long, a veteran horror and science fiction writer closely associated with the H. P. Lovecraft circle.

Trivia · 8 facts

  • Cover-dated Fall 1948, published under the B&I Publishing Co. Inc. imprint — the first issue of what became a 174-issue series running through August 1967, making it one of the longest-running horror anthologies in American comics.
  • Widely documented as the first ongoing horror-comics series in the American comic book medium, predating EC Comics' horror titles by roughly a year and a half.
  • Primary scripter for the debut issue was Frank Belknap Long, a prolific pulp horror and science fiction author associated with the Lovecraft circle; key artists included Edvard Moritz (cover and 'The Werewolf Strikes'), Fred Guardineer ('The Living Ghost'), Max Elkan ('It Walked by Night'), King Ward ('Haunted House'), and Al Ulmer ('The Castle of Otranto').
  • The issue contains a seven-page abridged comics adaptation of Horace Walpole's 1764 gothic novel The Castle of Otranto — one of the earliest examples of literary gothic fiction being adapted for the comic book medium.
  • The Living Ghost story marks the first appearance of the Institute of Psychic Research within the ACG universe, and its storyline — introducing the demonic entity Malevo, described as Satan's first lieutenant — was explicitly continued in subsequent issues.
  • The 52-page issue carried a cover price of ten cents and was edited by Richard E. Hughes (credited as Richard E. Hughes), who would serve as editor for the title's entire run and later write the majority of ACG's scripts under numerous pseudonyms.
  • Charles Atlas appears in the issue as an advertiser — the famous mail-order bodybuilding advertisement, a ubiquitous fixture in mid-century comics, is indexed as a character/entity presence in this issue.
  • The series was reprinted in multiple collected formats: A+ Comics and A-Plus issued early reprints (1990–1991); PS Artbooks produced a hardcover collected-works edition covering issues 1–83; and Dark Horse Comics published a deluxe Archives hardcover series (beginning 2012) collecting the early issues, with a foreword by Bruce Jones.
