Mansion of Evil #129

An early graphic novel. Historian Martin O'Hearn calls it the the "First (or Second) Modern Graphic Novel", but it depends on the definitions of "modern" and "graphic novel" one is using. (It is unknown whether this or It Rhymes with Lust (St. John, 1950 Series) was released first)
