National Comics #19

In "The Black Fog Mystery," the war-torn sands of Iraq become a battleground of ancient power and modern intrigue, as Merlin unleashes legendary relics—Goliath, Noah's Ark, and the Tower of Babel—to counter Nazi ambitions. Written, drawn, and inked by Fred Guardineer, this 1942 adventure blends myth and espionage in a story that’s as bold in concept as it is grounded in its era. The cover, a striking collaboration by Lou Fine, captures the mystery’s eerie tone with a haunting, fog-wreathed silhouette.
