Abstract: A display holder having track members for securely gripping and holding differently sized posters, signs and advertising materials. The track members comprise elongated extrusions having one or more flange members thereon which mate with corresponding elongated ribs on the backing member of the display holder. The advertising materials are inserted on the display holder so that at least one edge thereof is positioned between a flange member and a rib. The panels are held securely in place by tension. A plurality of frame-like members are preferably positioned on the exterior edges of the backing panel.
Abstract: An improved mounting bracket for a coil spring mounted poster display structure. The bracket comprises a metal plate having at least two stepped levels with a threaded hole formed through each level. The bracket is adapted to fit between adjacent coils of the spring so that the holes in the bracket are parallel to the axis of the coil spring. The coil spring is fastened to the poster display structure by a pair of mounting bolts which are positioned through corresponding holes in the structure and screwed into the holes in the bracket. The stepped levels in the bracket insure that the holes in the bracket will properly align with the holes in the display structure.
