A Circus of Hells by Poul Anderson - Chris Achilleos cover (1978)
A Circus of Hells by Poul Anderson was first published in 1970. This is the Sphere edition from 1978 with cover art by Chris Achilleos. I've got one of Chris's art books somewhere and liked to think I was a bit of a fan but this is a new one on me. It is rather nice. And here it is again without the words.
