The Spectre #3

A massive, glowing villain looms in the foreground, radiating menace as the ghostly white Spectre swoops in from the upper right — while a purple-costumed female figure watches from the left against a blazing cosmic sky above a vulnerable city. Neal Adams' cover art for this 1968 DC title crackles with dramatic tension, framing a threat to "Gateway City" that the Spectre may already be too late to stop. With Mike Friedrich writing and Adams handling both pencils and inks inside, this is a genuinely striking chapter in the Spirit of Vengeance's Silver Age run.
