MARVEL MYSTERY COMICS #4

Coverless and incomplete: both covers and most of the book are gone. Ten leaves (20 pages) remain: the complete 10-page Sub-Mariner story by Bill Everett, from the opening splash to the final page signed "Bill Everett '40" (pages 4-5 are not photographed); Masked Raider pages 5-8; both pages of the text story "Warning Enough"; and the first four pages of Electro's first appearance, including his splash page. The Human Torch story and the rest of the book are missing. The paper is tanned, with brittle, chipped edges and small marginal tears.

Marvel Mystery Comics #4 sits at the foundation of the Timely line that would become Marvel Comics, carrying the twin marquee features of the early Golden Age: Carl Burgos's android Human Torch and Bill Everett's antihero Sub-Mariner. This issue also delivers the debut of Electro, one of Timely's lesser-remembered but historically documented early costumed characters, cementing the number as a recognized first-appearance book rather than a simple run issue. Books from Timely's earliest output survive in tiny numbers, and any 1940-dated copy tying together these creators and features holds standing well beyond its cover date.

Demand for this title is anchored by the enduring collector appetite for pre-war Timely material and by the scarcity that governs the entire early Marvel Mystery run. The certified population is thin and concentrated in low grades, with the census topping out well short of the mid-grade tier and no high-grade certified examples recorded at all. That structure produces steep, non-linear pricing: incremental grade improvements command outsized premiums because so few upgrade candidates exist. The offered copy is coverless and partial, placing it below the certified brackets, but its surviving Bill Everett Sub-Mariner pages preserve genuine appeal for readers and completists chasing the story content of an otherwise unattainable book.

Buyers here are advanced Golden Age specialists, Timely and Sub-Mariner collectors, and investors treating scarce first-appearance material as blue-chip. Complete graded copies trade almost exclusively through auction at strong five-figure levels even in low grade, while intact mid-grade examples are rare enough to be event pieces. Coverless and incomplete copies occupy a distinct value tier, serving collectors who want authentic period pages and creator content at a fraction of the cost of a certified complete book; such copies trade privately and reward careful assessment of exactly which leaves survive.
