Abstract:
A single module for assembling a composite graphical image-bearing assembly comprising:a graphic display board having: front and back surfaces with a board thickness therebetween; first and second parallel perimeter edges with a board width therebetween; and third and fourth parallel perimeter edges with a board height therebetween; at least one bridging member secured to the graphic display board back surface, each having; a pair of spacer portions having first surfaces facing and secured to the graphic display board back surface; and a plate portion bridging the spacer portions and defining a channel between the spacer portions: and wherein there are exactly four bridging members; and each such bridging member is centered along an associated one of said perimeter edges and recessed from said associated perimeter edge by an associated offset; and wherein said single module being a first module in combination with a second such module wherein: the offsets of the first module and of the second module are effective to permit: back-to-back nesting of the modules with their boards aligned with each other but their bridging members aside each other so that the bridging members of each board may contact the back of the other board; and edge-to-edge assembly of the modules with a connecting bar extending through a channel of the first module and a channel of the second module.
