Creation Story
The Flash is the character whose first appearance is credited with starting the Silver Age of comics. By 1956, DC’s superhero line had thinned substantially; Golden Age heroes like the original Flash (Jay Garrick), Green Lantern (Alan Scott), and Hawkman had been shelved years earlier. Editor Julius Schwartz and writer Robert Kanigher proposed reviving the Flash concept with an entirely new character rather than resuming Jay Garrick’s story.
Showcase #4 (October 1956) introduced Barry Allen, a police forensic scientist in Central City who gains super-speed when lightning strikes a chemical shelf in his lab. Kanigher scripted the debut; Carmine Infantino pencilled the interiors and designed the now-iconic red costume with the lightning bolts; Joe Kubert drew the cover. Infantino’s design broke from Jay Garrick’s First Golden Age Flash visually (Garrick wore a Mercury-helmet with silver wings; Barry wears a form-fitting red-and-yellow speedster suit).
Showcase was DC’s try-out anthology title, similar in function to Marvel’s Strange Tales or Tales to Astonish a few years later. The test was whether a superhero book could sell in 1956 at all; readers had largely moved to romance, western, and horror comics. Showcase #4 moved strongly enough that DC greenlit a Flash solo title two years later, and the commercial response kicked off a wave of superhero revivals (Green Lantern, Hawkman, Atom, Justice League) that defines DC’s Silver Age.
The most important single-issue key in DC history
Showcase #4 is arguably the most historically important single comic book DC has ever published. Not because of the character alone, but because of what it started. Every superhero book that followed on either side of the industry through the 1960s traces some commercial debt to Showcase #4 demonstrating that the genre was still commercial in 1956.
High-grade copies have crossed $500,000 at auction. Low-grade reader copies trade in the mid-five-figure range. The book’s collector weight has held steady across every Flash film, television series, and character absence in the publishing history.
Why Barry had to die
Barry Allen’s death in Crisis on Infinite Earths #8 (November 1985) was DC’s single most consequential character death of the 1980s. Marv Wolfman and George Perez designed Crisis as a company-wide reset, eliminating the multiple-Earths structure that had accumulated since The Flash #123 (1961). Barry Allen’s death was not a casual event; it was the editorial statement that DC was committing to permanent, stakes-bearing change.
Wally West, Barry’s sidekick Kid Flash, took over the Flash title in 1986 and held the role for twenty years. Wally is many readers’ Flash rather than Barry; the CW’s television adaptations, the Young Justice animated series, and several comics runs prioritize Wally over Barry. Barry’s 2009 return in The Flash: Rebirth restored him to primary-Flash status and set up the Flashpoint event that rebooted DC’s continuity in 2011.
Collector context
Showcase #4 is the Flash key and a required DC Silver Age book. Its pricing sits alongside Action Comics #1 (Superman) and Detective Comics #27 (Batman) as one of DC’s three foundational Silver Age-era keys, though Action #1 and Detective #27 are Golden Age books and Showcase #4 is the Silver Age counterpart.
Secondary keys: Flash Comics #1 (1940) is Jay Garrick’s first and a Golden Age key. The Flash #105 (1959) is Barry’s first solo title. The Flash #110 (1960) is Wally West’s first appearance as Kid Flash. The Flash #123 (1961) is the Flash of Two Worlds issue and the first DC Multiverse story. The Flash #139 (1963) is the first appearance of Reverse-Flash. Crisis on Infinite Earths #8 (1985) is Barry’s death issue.
