44-page one-shot considered to be the first autobiographical comic wherein the creator utilizes the medium to confess deeply personal traumas resulting from a Catholic upbringing clashing against a post-publication diagnosis of obsessive-compulsive disorder

Inspired creators including Art Spiegelman, Robert Crumb and Jim Woodring

First printing approximate copies: 55,000

Subsequent printings can be identified from the first by the absence of an illustration of the virgin Mary in the background behind a full text panel on page 23 (tap cover and swipe for clarification)
