Superman en Batman #5/1967

In "Het spel der pseudoniemen!", young Lex and Superboy start as friends, but a mishap at Luthor's lab—where Superboy accidentally destroys the facility and causes Lex to lose his hair—sparks a bitter grudge. As the rivalry ignites, a battle of wits and disguises begins, with both boys testing their mettle under false identities. Written by Jerry Siegel and illustrated by Al Plastino, this 1967 tale captures a classic moment in the early history of two future icons.
