Abstract
A magnetic letter board assembly having a magnetic letter board and removably magnetically secured magnetic graphic indicia bodies, wherein the front surface of the board has a pair of inwardly converging walls and a wall bridging the inwardly converging walls, and the graphic indicia bodies have a recess formed with a pair of inwardly converging walls and a bottom wall bridging the inwardly converging walls conforming to the walls and bridging wall of the board, for cooperative removable securement of the indicia bodies on the board. The graphic indicia bodies comprises of magnetic flexible integrally formed graphic indicia and background members formed to fit the board.

A magnetic letter board assembly comprising the combination of a substantially rigid magnetic letter board composed of one material and a plurality of removably magnetically secured magnetic graphic indicia bodies each composed of a material different from and appreciably more flexible than said letter board and arranged on said board to display a message, wherein the front surface of said board and the rear surface of each of said graphic indicia bodies each have a pair of cooperating inwardly converging walls and a surface bridging said walls, each defining lands and grooves and a recess between them extending in the same direction, and each of said graphic indicia bodies has a flexibility permitting the selective lifting of said graphic indicia body from said board and its manipulating along said walls and surface for remounting on said board.
A magnetic letter board assembly comprising the combination of a substantially rigid letter board composed of one material and a plurality of removably magnetically secured magnetic graphic indicia bodies arranged on said board to display a message, wherein (a) the combined area of said bodies does not exceed the area of said board, (b) at least the front surface of said board or the rear surface of each of said graphic indicia bodies has a magnetic field and the other surface is attracted to said magnetic field, and (c) the front surface of said board and the rear surface of each of said graphic indicia bodies include means for orienting said bodies relative to said board and to each other, said means including, on the front surface of said board and the rear surface of each of said graphic indicia bodies a pair of cooperating inwardly converging walls and a surface bridging said walls, each defining lands and grooves and a recess between them extending in the same direction, and each of said graphic indicia bodies are adapted for selective lifting of said graphic indicia body from said board and manipulated along said walls and surface for remounting on said board.
