Abstract: A poster holder having a first member, a second member moveable away from the first member to an open position and moveable towards the first member to a closed position, the second member cooperating with the first member to secure the substrate in the closed position, a controller configured to selectively energize at least one portion of an energizeable image on a substrate detachably securable between the first member and the second member in the closed position, and an electrical power source connected to the controller. The poster holder is useable in a display that includes a poster formed of a substrate and an energizeable image formed thereon. Methods of displaying an energizeable image using the poster holder are set forth.

Abstract: A polishing belt is made from a woven base layer with a matte affixed thereon. The matte includes a plurality of batting fibers with abrasives. These abrasives are permanently mounted on the batting fibers. The abrasives can include abrasive particles impregnated or securely bonded to the shafts of the fibers. Alternatively, wool fibers can be used. These wool fibers can have spaced ridges along the shafts of the fibers. Otherwise, edges of the fibers themselves can be used as an abrasive. The fibers with such edges can have a triangular or star shape in cross section whereby the edges are formed. These edges will act as the abrasive. With this belt, it is possible to polish paper. The paper is passed by the polishing belt. The paper will move at a first speed and the polishing belt will move at a different second speed. The abrasives on the fibers of the polishing belt will abrade the surface of the paper.
