Abstract: A display apparatus for presenting changeable signage appropriate for use with backlit sign frames. Information-bearing inserts are supported in pockets on a display film which has a plurality of transparent panes through which the inserts may be displayed. Each end of the display film is loosely wound around a roller, and the remainder of the display film can be viewed through a translucent front display window. The rollers are coupled with multilink endless chain and are mounted on brackets which also support the display windows. The front window is hinged to allow it to be swung open for access to the display film for changing the inserts and for scrolling the display film so that a different set of inserts is visible through the display window. The display apparatus is supported by an existing sign frame through the use of fasteners spaced along the brackets and along the perimeter of the existing sign frame.
