The key trap is a binding variant, not a separate imprint: Peake in Print records copies bound in 'brilliant scarlet-vermilion buckram' with better-quality gilt as a later, unacknowledged reprint reputedly dating from 1952 — the imprint and sheets otherwise resemble the 1950 first, so the buckram and the superior gilt are the tells. Weybright & Talley 1967 and Ballantine 1968 are 'first thus' reprints. No book-club edition is documented in the sources consulted.
