Blackhawk #42

A massive yellow robot known as the Iron Emperor dominates this 1951 Quality Comics cover, clutching a screaming woman in red with one mechanical hand while wielding a spiked mace in the other — a genuine menace rendered with Reed Crandall's sharp, dynamic linework. Below, several Blackhawk squadron members in their distinctive blue uniforms fire pistols upward in a desperate attempt to bring the giant machine down amid a field of rubble. With 52 big full-width pages packed into a ten-cent issue, this is Golden Age adventure at its most vivid.
