Marathon Man

No book-club-specific point is documented for this title in the sources consulted. US club copies of Delacorte titles of this period are identified in the usual way — no price at the jacket flap and a blind-stamped square or dot on the rear board, with lighter bulk and lower-grade paper than the trade book. Note that a previous owner's personal blindstamp at the half title is a provenance mark, not a club tell, and should not be confused with one.
