The Sword in the Stone. by WHITE, T.H

London, Collins, 1938. . First edition, 8vo, vignette illustrations by the author, spotting to terminal ff., otherwise internally very good, publisher's cloth, minor bumping to fore-corners and slight shelf-lean, otherwise very good, dust-jacket, some loss to head of spine, closed tears to lower edge of lower panel and foot of spine, jacket slightly darkened at spine as usual, but still a very good example of a scarce work in the original dust-jacket.
The first, and most famous, part of the tetralogy The Once and Future King, originally published as a stand-alone work. The future King Arthur's formative years, under the aegis of Merlin and comprising a series of literally transformative experiences.
