A display system for two-dimensional displays wherein images are applied (e.g., photographically, printed or the like) to transparent sheets and transported through a viewing machine, the sheets being sequentially positioned in a back-lighted viewing window. The sheets are suspended from rods and stored behind the back-lighting area. The rods are arranged in a desired sequence in a storage rack having an entrance and exit. A chain is entrained on a circuitous pathway through the machine. The pathway starts at the exit end of the storage rack referred to as a pick-up station, then passes over the back-lighting area, extends downwardly between the back-lighted area and the window, passes under the back-lighting area and behind the stored display sheets to a return station that receives the sheets and directs them to the entrance to the storage rack, and then back to the pick-up station. The images are inverted on the sheets with the sheets suspended from the rods, e.g., in storage as they are inverted when positioned in the viewing window. As the sheets travel through the viewing window a guide channel lightly grips the sheets to keep the sheets taut for viewing.
