Inspiration came from 2 places for this one, first off the beautiful and classic 70ies covers of the comic Ghost Rider. And secondly, the indispensable Gone and Forgotten blog, on which the editor wrote:
"put a gorilla on the cover, and it would sell. [And] additionally [...] fire, motorcycles, the color purple and interrogatives". For his blog: gone-and-forgotten.blogspot.com
