Abstract
A preferred sign frame and poster display device holds a sign or poster securely on all edges and allows for expansion and contraction of the sign. The sign frame and poster display device preferably includes a plurality of elongated frame sections, each having a base member and a hinged cover member. At least one slide member is mounted inside the base member for slidable movement generally in a plane parallel to the sign and poster surface. Each of the slide members includes a post member adapted to be received within a corresponding aperture near the perimeter of the poster or sign panel. Preferably, a retainer member is pivotally interconnected with a portion of the slide member for movement into and out of interlocking engagement with the peg or post after the poster or sign panel has been installed thereon in order to reinforce the peg or post and to securely retain the poster or sign panel in place during installation.
