Adventure Comics #48
☆ Be the first to review + Add to your collection — Join freeAdventure Comics #48 marks the first appearance of Rex Tyler, the original Hourman — one of the founding members of the Justice Society of America — introducing a superhero whose power source, the performance-enhancing drug Miraclo, carried an implicit addiction subtext that set him apart from every costumed hero that preceded him. That premise seeded decades of storytelling about dependency and identity, making this debut unexpectedly resonant long after the Golden Age closed. The issue also continued the ongoing Sandman feature with Wesley Dodds and his newly introduced partner Dian Belmont, giving readers two proto-JSA members in a single anthology package and accelerating Adventure Comics' transition from a general-adventure title into a superhero showcase. Together, both features in this issue fed directly into the formation of the first superhero team in All-Star Comics #3 later that same year.
In "Presenting Tick-Tock Tyler, the Hour-Man," chemist Rex Tyler gains extraordinary abilities after developing a mysterious compound called "miraclo," using his new powers to protect the innocent and turn a criminal around. Written by Ken Fitch and illustrated by Bernard Baily in a striking, unified effort across pencils, inks, and lettering, this 1940 adventure introduces a hero whose time-bending potential is just beginning to unfold. The cover by Bernard Baily captures the moment with dramatic flair, setting the stage for a story rooted in early superhero idealism.

Writer Ken Fitch and artist Bernard Baily — already working together on other DC features — co-created the Hour-Man for Adventure Comics under editor Vin Sullivan, with Baily handling pencils, inks, and lettering on the debut story. The timing was remarkable: Baily had co-created the Spectre with Jerry Siegel just one month earlier in More Fun Comics #52, meaning he introduced two charter JSA members within roughly thirty days of each other in early 1940. Notably, the debut story presents Rex Tyler already fully operational — costume designed, Miraclo formulated, and a post-office-box ad placed to solicit requests for help — with no traditional origin sequence recounting how he got there.
Trivia · 8 facts
- First appearance of Rex Tyler / Hourman (spelled 'Hour-Man' in early issues), co-created by writer Ken Fitch and artist Bernard Baily; cover-dated March 1940, on sale February 2, 1940.
- Hourman's power stems from Miraclo, a self-synthesized compound that grants enhanced strength, speed, and senses for exactly one hour — a built-in time limit that defined the character and was later reinterpreted as an addiction mechanic in modern stories.
- Artist Bernard Baily had co-created the Spectre (with Jerry Siegel) the immediately preceding month in More Fun Comics #52, making him the only Golden Age creator responsible for two founding JSA members debuting within the same spring season.
- The Sandman feature in this issue — titled 'Death to the D.A.' — involves Wesley Dodds and Dian Belmont protecting District Attorney Belmont from a conspiracy of high-society criminals; this story was later reprinted in DC's Golden Age Sandman Archives Vol. 1.
- Dian Belmont, who had just been introduced as a regular cast member in the preceding issue (#47), appears here as an active partner to the Sandman rather than a passive love interest — a characterization notably ahead of its time for 1940.
- Hourman's run in Adventure Comics extended from issue #48 through #83 (1940–1943), and he was a charter member of the Justice Society of America beginning with All-Star Comics #3 (Winter 1940), though he became the first JSA member dropped from active roster — replaced by Starman in All-Star Comics #8.
- Rex Tyler's origin was formally retold in Secret Origins Vol. 2 #16 (July 1987), confirming and expanding details from this debut, including his workplace at Bannermain Chemical Company.
- The issue is a multi-feature anthology also containing the 'Barry O'Neill' and 'Federal Men' (Steve Carson) strips, alongside 'Socko Strong' and 'The Diddle Family,' reflecting Adventure Comics' transitional identity as it shifted from general adventure to superhero anthology.
