The Counterfeiters (Les Faux-monnayeurs)

The true first edition is the French Les Faux-monnayeurs, Paris, Éditions de la Nouvelle Revue Française (Gallimard), 1925 — note the book is dated 1925 but was not placed on sale until February 1926, a well-known quirk dealers routinely cite. The first English-language edition is The Counterfeiters, translated by Dorothy Bussy (whose rendering remains the standard English text), published by Alfred A. Knopf, New York, 1927, stating "First American Edition" in publisher's cloth (blue cloth, roughly 365 pp.). The Cassell London edition did not follow until 1931, so the 1927 Knopf is the first edition in English worldwide, not merely the first American.
