Weird Book of the Week

Last time on Weird Book of the Week, we tackled a touching tale of Dinosaur Nazis. This time, well, it's not so much the contents of the book so much as the cover:
Recursive Centaurs!
It's a centaur... but sorta recursive? Um... I don't... what? If I were a bigger Bradbury fan, I'd snap this up in a heartbeat. It is a real book, but I don't know if Amazon has this particular edition (the 1971 Corgi books edition).
