Paleo book cover

This cover is for the other story of the Doubledown book. It's a short story by David Liss that follows a loser who slowly discovers the power of the old gods from cavemen days. The main image comes from a symbol used in the book, drawn in blood, that empowers our anti-hero. I've always wanted to use Gill Sans UltraBold and make it work, and I think it fit this cover perfectly.
