Above is a collection of covers from Italian illustrator Benedetto Caroselli for Grandi Edizioni Internazionali, all referencing the concept of Hell, and the entities conceptualized to inhabit the pits therein, including Satan, devils, demons, and incubui. These were made for the terror series I Capolavori della Serie KKK Classici dell’Orrore. You can see more Hell covers at this link and this one, and in this collection.
Caroselli is strictly the pits.
