Superman #225

Superman #225 pulls readers in immediately with one of the most striking cover conceits of 1970: Superman himself standing before a caged figure wearing his exact costume, fists clenched, as the prisoner pleads to be freed or killed after a year of imprisonment — and Superman coldly replies, "All right, I'll kill you!" Curt Swan's pencils and Murphy Anderson's inks give both figures a tense, almost mirror-image quality that makes the central mystery impossible to ignore. With Leo Dorfman scripting and Curt Swan on interior art, "The Secret of the Superman Impostor!" promises a story built around identity, deception, and a confrontation that defies easy answers.
