“The Soft, Sweet Lips of Hell” by O’Neil, Adams & Steve Englehart
Diversions of the Groovy Kind has posted The Soft, Sweet Lips of Hell by (writer) Denny O’Neil and (artists) Neal Adams & Steve Englehart which appeared in Vampirella #10 (December 1970)! Englehart went on to fame as a comic book writer. I had no idea he began his career as an artist.
Thanks to Diversions for giving us another look!
