The Detective Comics #400 in context

Why collectors care

The first appearance of Man-Bat, cover-dated June 1970, in the landmark 400th issue of Detective Comics. The Neal Adams cover is among the most admired of the era, and the anniversary numbering adds collector appeal.

How to identify it

Detective Comics #400, June 1970. The Adams cover showing Man-Bat looming over Batman is the quickest visual confirmation.

Common mistakes

Facsimile editions exist and reproduce the Adams cover faithfully. Confirm the 1970 printing in the indicia.

Grade considerations

The dark, atmospheric cover shows spine ticks and corner wear plainly. High-grade copies are scarce and carry a steep premium.
