Cosmic Horror Coloring Book

As a group of intrepid astronauts venture into the cosmic realms, they are met by a series of unforeseen horrors. Their space vehicles are overtaken by tentacled monsters, a skeletal creature invades the spaceship and a super-strong robot tears unwitting humans limb from limb, among many other terrifying images. 

Artists Juan and Santiago Callé have imagined a world of horror in this that you can add your own colorful touches to.
