The Detective Comics #225 in context

Why collectors care

The first appearance of the Martian Manhunter, cover-dated September 1955, created by Joseph Samachson and Joe Certa. J'onn J'onzz is a Justice League founder, and some historians treat this book as an early marker of the Silver Age transition.

How to identify it

Detective Comics #225, September 1955, in the story "The Strange Experiment of Dr. Erdel." The character debuted as a backup feature, not a cover story.

Common mistakes

Expecting a Martian Manhunter cover. The issue is a Batman cover with the debut as an interior backup, which surprises buyers who have only seen slab photos.

Grade considerations

A mid-50s book with limited high-grade survival. Cover gloss, spine ticks, and page tanning limit most copies.
