The Silmarillion. by TOLKIEN, J. R. R - 1977: Edited by Christopher Tolkien.

London: George Allen & Unwin,, 1977. First edition, first impression, domestic issue. The Silmarillion is the mythology of Middle Earth, hinted at but not fully explored in The Hobbit and The Lord of the Rings. The stories it comprises were written by Tolkien intermittently between the First World War and his death in 1973, and were published posthumously by his son Christopher.
The publication history of The Silmarillion is complicated. Hammond identifies "export" and "domestic" issues, with no priority. Hammond describes the "export" issue first and then the "domestic" issue. The "export" issue was printed by William Clowes and carries no price on the dust jacket. The "domestic" issue notes that the printing was "by offset lithography by Billing" and carries a price on the dust jacket. This copy is from the "domestic" issue. Octavo. Original dark blue cloth, spine lettered and decorated in gilt, top edge blue. With dust jacket. Internal map and folding map printed in red and black to rear. Head of spine very slightly bumped, minor browning to front free endpaper; head of jacket spine slightly rubbed, not price-clipped: a near-fine copy in a near-fine jacket. Hammond & Anderson A15a.
