Mulata by Miguel Ángel Asturias; English trans. by Gregory Rabassa. 1982 mass market paperback from Avon-Bard. The Boschian cover art isn’t credited; neither is the designer credited, although my assumption is that it is Sidney Feinberg, who is credited as designer on Avon-Bard’s edition of Gabriel García Márquez’s novel In Evil Hour.
