Une aventure d'Hatchi - La Spirale infernale #[nn]

Published in 1991 through L'Association, this solo effort by Jean-Pierre Duffour — who handled every creative role from writing to lettering — presents La Spirale infernale, an adventure starring Hatchi. With Duffour's hand guiding every line on the cover as well, this is a remarkably unified personal vision from a single creator working in full control of his story.
