Abstract: A holder is made from flexible material and is held in tracks of a conventional reader board. The holder has upper and lower edges that lie in a common plane and are normally separated by a first distance. A middle region lies forward of the common plane. The middle region includes channels having downwardly converging surfaces for removably receiving a decoration with similarly converging sides in wedging engagement. At removal, a person uses a suction cup to grip the decoration. Force applied to the suction cup pushes the decoration and the holder middle region toward the reader board, causing the holder middle region to flex and increase the distance between the upper and lower edges of the holder, hence moving the edges farther into the reader board tracks. The holder lower edge is then unable to slide upwardly and come out of the reader board and fall on the person.

Abstract: A unitary flexible information presentation board having self-suction is disclosed. The board comprises a unitary flexible sheet having an exterior convex surface, an interior concave surface and a beveled periphery. Each surface is uniquely tapered to allow the interior concave surface, when placed against a substrate, to form a vacuum seal against said substrate, upon application of pressure from the exterior convex surface and thereby adhere to the substrate by self-suction action, without the need for an extraneous suction cup member. It thereby resembles an oversized suction plate upon which information can be prominently displayed. The board can be removed, attached and reattached to substrates without damaging these substrates. The board can be lifted off the attached substrate by lifting of the beveled periphery of the board. Lifting of the periphery of the board releases the vacuum seal formed.
