Publication history
1951, New York: The Viking Press, February 23, 1951, hardcover
In his limited-edition pamphlet, Collecting Mystery Fiction #9, Rex Stout's Nero Wolfe Part I, Otto Penzler describes the first edition of Curtains for Three: "Gray cloth, front cover printed with red lettering (and decoration on front cover only) and black rules; rear cover blank. Issued in a black, orange and white dust wrapper." In April 2006, Firsts: The Book Collector's Magazine estimated that the first edition of Curtains for Three had a value of between $300 and $500. The estimate is for a copy in very good to fine condition in a like dustjacket. 1951, New York: Viking (Mystery Guild), 1951, hardcover
The far less valuable Viking book club edition may be distinguished from the first edition in three ways:
 The dust jacket has "Book Club Edition" printed on the inside front flap, and the price is absent (first editions may be price clipped if they were given as gifts). Book club editions are sometimes thinner and always taller (usually a quarter of an inch) than first editions. Book club editions are bound in cardboard, and first editions are bound in cloth (or have at least a cloth spine). 1951, London: Collins Crime Club, October 22, 1951, hardcover
