Each of these horror / monster book covers features monster feet and a different highlight color. There are hairy feet that could belong to a werewolf, green feed that could belong to a zombie or goblin, and red feet that could belong to a demon or vampire. The background is a grungy white with rips and tears.
This fantasy illustrated book cover features an illustration of the devil or demon holding a trident on one hand and a chain on the other. Fire is at his feet. At the bottom of the cover are evil warriors, some on horses and wielding shields and weapons.
