Abstract: A changeable sign includes a flat magnetizable sheet metal sign board, and a plurality of trapezoidal segments of magnetic sheet material sized and arranged to form segmented alphanumeric characters magnetically adhered to the board. The board also includes space to apply a sheet of magnetic material containing printed information. Semi-invisible guidelines on the board, such as glossy lines on a flat background of the same color, guide the positioning of the segments to form the characters. The segments are formed with non-acute angle corners to maximize adherence at their corners. The segments are rearranged to form different characters and can be repositioned at will on the sign board over the guidelines to completely alter the sign format.

Abstract: A sign for displaying information including numerals, having a background member including ferromagnetic material and a plurality of substantially similar individual character elements which may be magnetically attached to the background member to cooperatively form individual digits. Seven or fewer individual character elements, each preferably having the identical elongated hexagonal shape, are combined to form each digit of a price being advertised. Each such character element is made of flexible sheet material including comminuted permanently magnetized material, and an outer surface of each character element may be coated with light-reflective or fluorescent paint of a color contrasting with the color of the background member. Alternative labels may be magnetically mounted on the background member to identify the product for which the price is advertised.
