"Master Harold"...and the boys

US true first: Alfred A. Knopf, New York, 1982 — the census claim is confirmed. The play premiered at the Yale Repertory Theatre in March 1982 and reached Broadway in May 1982, and the Knopf hardcover is the first book publication; no earlier South African edition was located in the sources consulted (a negative finding limited by those sources). The UK Oxford University Press edition of 1983 (ISBN 0192813943) followed, and is catalogued as an Oxford paperback rather than a competing hardcover first — so Knopf 1982 is unambiguously the edition to collect and there is no UK/US split here. First-thus trap: the Samuel French acting edition and the Vintage International reissue (ISBN 9780307475206) are later publications.
