Sir Gawain and the Green Knight (eds. J.R.R. Tolkien & E.V. Gordon)

UK only. Clarendon Press, Oxford, 1925 is the sole true first — there is no separately set US first edition. Two 'first thus' traps: (1) the revised second edition prepared by Norman Davis (Clarendon Press, 1967) reuses the Tolkien-Gordon text but is a later edition, not this book; (2) Tolkien's Modern English verse translation, published as Sir Gawain and the Green Knight, Pearl, and Sir Orfeo (Allen & Unwin, London, 1975; Houghton Mifflin, Boston, 1975), is an entirely different work and is frequently mis-catalogued as the '1925 Tolkien Gawain.' This 1925 scholarly edition is Tolkien's collectible book debut.
