A display having mating door sections includes a frame, upper and lower parallel, spaced apart door mounts affixed to the frame, and doors mounted to the frame between the door mounts for securing panels thereto. The door mounts each include openings in vertical alignment with one another for mounting the doors. Each door is mounted to the display frame, between the upper and lower door mounts. Each door has first and second mating door sections joined to one another at a mating juncture. The mating door sections each have a raised rim around a rear portion and upper and lower edges of the sections defining a central recessed region. The recessed region has a plurality of apertures therein, each defining a raised sleeve portion and an opening therein. Each door includes upper and lower pivot pins at about the rear portion at the upper and lower rims respectively. The pivot pins extend transversely from the upper and lower rims and are configured for insertion into the door mount openings for pivotal movement of the doors. The doors are removable from between the upper and lower door mounts. The door sections recessed regions are each configured for mounting an associated panel thereto. Each associated panel resides within the recessed region below the door section raised rims.
