Strange Adventures #111

From DC's Strange Adventures line comes this 1959 sci-fi gem featuring "Secret of the Last Earthman!" — a story that captures the era's flair for cosmic dread. The cover by Gil Kane (pencils) and Bernard Sachs (inks) drops us right into the tension: a lone man trapped inside a transparent isolation booth, pressing his hand against the glass while two green-skinned Martian invaders in helmeted armor loom on either side of him. The cover's own caption says it all — everyone on Earth has vanished except him, and the Martians are keeping him alive for reasons unknown, making for a genuinely unsettling ten-cent thrill.
