London, Gollancz, 1987. First Edition. First Impression. Hardback. A fine copy. One of Pratchett's most loved novels. Signed by the author without inscription. The signature is an early one. The fourth Discworld novel and one of only 3,950 copies, becoming increasingly hard to find in such condition. Very light pushing to the spine tips. A wonderful copy. Cover art by Josh Kirby [8232, Hyraxia Books].
