Got in some rare 1st printings of the PHB and DMG. They each have the yellow-orange endpaper inside covers, yellow and red striped fabric spine inlay, and binding stitching is 5/8″. The later, much more common printings went with white flypaper, dispensed with the fabric spine inlay, and hid the stitching (now 1″).
