The now-cancelled CW series Chilling Adventures of Sabrina was not the first time the "Teenage Witch" did actual horror...
... in 1972, she hosted her own series of horror stories told in the Archie "vein" as you can see in this never-reprinted (in color) terror-tale...
Now there's an ambiguous ending if ever I heard one...
In 1971, the Comics Code Authority loosened its' regulations regarding monsters, allowing limited use of "classic" creatures including vampires, werewolves, and zombies.
While DC and Marvel went monster-happy, unleashing new strips and several new titles, Archie Comics' response was this book with an unusual combination of horror writing and Archie house-style art, which tended to conflict with the theme of the stories!
To be fair, writer Frank Doyle, penciler Dan DeCarlo, and inker Rudy Lapick tried their best with this tale from Chilling Adventures in Sorcery as Told by Sabrina #1 (1972), but it just doesn't work.
After two issues, the series was revamped (pun intended) into a more-traditional horror title with non-cartoony art by Gray Morrow and associates, dropping Sabrina as the hostess.
