Superman #351

Superman faces a genuinely unsettling threat on this 1980 DC cover by Ross Andru and Dick Giordano — a hulking pink creature whose body is covered with nine distinct human faces, reaching toward the Man of Steel with massive clawed hands while Superman recoils, one arm paralyzed by the monster's touch. The cover promises two full stories, including "The Fiend with Nine Faces!" plus a circus adventure featuring the mischievous fifth-dimensional imp Mr. Mxyzptlk, who appears in miniature at the bottom corner. With Gerry Conway writing and Curt Swan on interior art, this issue delivers the kind of imaginative Silver Age energy that made Superman comics so compelling well into the Bronze Age.
