Detective Dan: Secret Operative 48

From 1933, Norman Marsh’s Detective Dan: Secret Operative 48 debuted as a single-issue comic from Humor Publishing Co., blending the era’s pulp detective thrill with the budding comic medium. Marsh both wrote and illustrated this lone installment, crafting a straightforward crime-fighting narrative that stands as a modest, self-contained snapshot of early 1930s comics—a brief, creator-driven experiment before the genre exploded into ongoing series.
