DUEL IN THE SUN by Niven Busch                                            Popular Library, First Paperback Printing, 1946                          Condition: Near Very Good                                                                                                                                                                The earliest mass market paperback movie tie-in was Pocket Book #7, WUTHERING HEIGHTS (& maybe PB#1, LOST HORIZON, since both were published in 1939, the  year the movies were released).  But such tie-ins were not common during the first half of the '40s, so DUEL IN THE SUN (Popular Library #102) is an early example.  Pictured on the front cover are Gregory Peck and Jennifer Jones, and the movie reference is at  the bottom.  This is a solid copy, but there is some creasing on the covers and light to modest corner/edge/spine end wear. The lamination on the exterior is virtually all intact except for the upper right corner of the front cover. The front green-dyed page has a light crease from cover and there is minor page corner creasing on a few front pages.  Secure binding throughout & no markings or other wear on lightly toned pages.
