These 13

No book-club issue is documented for 1931. The working trap is the stated second and third trade printings: they match the first in binding and carry the same 1931 date, and are routinely offered as "first edition" on the strength of that date alone. The contents-page 280/208 error and the absence of any printing statement separate the first printing from them. The 299-copy signed issue is identified by its bracketed italic pagination and August 1931 limitation leaf, not by the trade points.
