Detective Comics #409

In "Man in the Eternal Mask!", Batman teams up with a troubled artist whose portraits are being grotesquely altered by a shadowy figure, leading to a chilling mystery that blurs the line between art and violence. With the artist’s latest work hinting at a hidden truth, the Dark Knight must unravel a pattern of mutilation before the killer strikes again—while the case unexpectedly ties back to a past case involving a masked assailant. Written by Frank Robbins and illustrated by Bob Brown, with inks by Frank Giacoia and letters by Ben Oda, the issue features a striking cover by Neal Adams and Dick Giordano.
