UK is the true first: Faber and Faber, London, 1967. The first American edition — Harper & Row, New York, 1967 — followed within the same year and is bound quite differently: half blue cloth over brown paper boards, silver decoration to the front board and silver lettering to the spine, collating [6], 7-184, [8] pp. Imprint and binding are the quickest separators. The census note giving a May 1967 UK date could not be confirmed; inscribed copies dated 8 June and 13 July 1967 are consistent with a mid-1967 UK publication, but the exact month is undocumented in the sources consulted.
