A display device having track members on two sides of a single backing member for securely gripping and holding differently sized posters, signs and advertising materials is disclosed. The track members comprise elongated extrusions having one or more flange members thereon which mate with corresponding projections or rib means on the backing member of the display device. The advertising materials are inserted on the display device so that at least one edge thereof is positioned between a flange member and one or more projections. 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.
