The New Centurions

This is the classic trap on this title. The book-club edition is otherwise identical to the trade first and its jacket even carries a printed price, so price presence alone will not sort them. Two documented tells decide it: the club jacket adds a "Book of the Month Selection" statement to the left of the price, which is absent from the trade first; and the club board carries a small square or round blindstamp at the lower right corner of the rear board near the spine, which is a different mark from the publisher's own larger blind-stamped Little, Brown / Atlantic device found on genuine firsts. Check both before calling a copy a first.
