Abstract
A display sign and a method of retrofitting a display sign has a number of conventional structural frame members about which a flexible facing material is attached. The frame members have rods fastened to surfaces thereof remote from the front of the facing. For larger signs adjacent frame members may be connected together by the facing material and have cooperating adjustment members which permit adjacent frame members to be moved apart to expand the size of the frame members and simultaneously stretch the facing. The frame members and the facing material are positioned within a display sign cabinet having an opening just slightly greater than that of the margin of the frame members, and the border of the frame members may be adjustably moved apart by a pivotal movement about the rods as a fulcrum on the frame is secured to framework within the sign housing to snuggly fit within the opening.
