Superboy #166

Neal Adams delivers a genuinely unsettling cover for this 1970 DC adventure: a mysterious figure in a flaming crown lies prone on a red slab inside a shadowy tomb, while Superboy flies in urgently warning two explorers — flashlight and all — to stop before they enter. The story title "Here Lies the Real Superboy!" teases a centuries-old secret waiting to be uncovered, setting a mood of ancient mystery that feels surprisingly eerie for a teen Superman tale. Written by Frank Robbins with interior art by Bob Brown and Mike Esposito, this is a solid slice of early-'70s DC storytelling wrapped in one of Adams's most atmospheric covers of the era.
