London, Gollancz, 1972. First edition, first impression. Hardback. A very good copy. First British hardback edition, preceded by the US edition(s). Winner of both the Nebula, Locus and Hugo awards. Condition: some foxing to the edges of the block, the jacket's in very good shape, just a little pushed to the spine tips and corners. Some soiling to the boards. [9445, Hyraxia Books].
