A versatile and user friendly display system. First and second sets of panel frames and a plurality of header frames are interchangeably connected so that the header frames are optionally above, between, or below the first and second sets of panel frames. The frame segments are connected by key members to allow relatively easy field repair and the adding or subtracting of additional frames. A hinge for hingedly connecting a pair of frames comprises at least one pair of straps composed of a flexible material. One strap is attached to the front edge of an elongate segment of one frame and the rear edge of an elongate segment of the other frame. The other strap is attached to the rear edge of the elongate segment of the one frame and the front edge of the elongate segment of the other frame. The attachment of the straps to the front edges defines a hinge axis about which the frames are rotatable through a first arc, and the attachment of the straps to the rear edges defines a hinge axis about which the frames are rotatable through a second arc. At least one elongate segment of a frame is formed as two parts wherein a first elongate member serves as a tie bar between a pair of frame segments and is adapted to provide an opening for insertion of a panel, and a second elongate member is removably attachable to the first elongate member and closes the opening to prevent insertion and removal of panels.
