Superboy #17

From 1951, this tenth-cent DC gem poses a tantalizing question right on its cover: "Which is the real Superboy?" The cover by penciler John Sikela and inker Stan Kaye delivers a genuinely fun scene — one Superboy soars overhead in full cape while a second stands confidently at the right, both watching a medieval-armored knight get clocked by a trumpet-wielding figure at center, with an archer poised in the background. It's a delightfully offbeat image that captures the era's imaginative storytelling spirit, with interior work by the talented team of writer Bill Finger, artist Curt Swan, and inker John Fischetti.
