The Children's Hour

No book-club printing is documented for the Knopf 1934. The practical tell is the copyright-page statement itself: a copy lacking the quoted 'First edition.' note is a later Knopf printing, and no binding or jacket variant substitutes for that check. The recurring misidentifications are the 1937 Hamish Hamilton (London) edition and the later collected and acting-edition reprints, all of which carry their own imprints and dates on the title page — read the imprint before the binding.
