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.
