Here's a unique publication, a never ending accordion! I'm still confused exactly where the story begins but its something about an astronaut, a caveman and then things happen and roles get exchanged and then the story starts again. On the inside is a night sky with what looks like the trajectory of the rocket as it speeds across space. Included at the end of these images are 3 from the site that sells this accordion (Uncivilized Books : Kozmo-Knot by Eero) as my copy of the book did not come with this rather interesting packaging.
Each page 2.5" and extended 2' 9.75", circumference 5' 7.5".
