ABSTRACT:
A literature display box for supporting literature on a horizontal surface includes a center and two end parts which interfit with the center part so that they may be adjusted laterally to provide lateral expansion or contraction of the box. The back and bottom of the center part are provided with guide tracks which interfit with fingers or tines projecting from the end parts. Interengaging stops preclude separation of the parts but include cam surfaces facilitating assembly. The parts include rearwardly extending legs cooperating with the lower front edge of the center part to support the display box inclined somewhat rearwardly on a horizontal surface. The parts are preferably made of durable molded plastic.
