  • Patent number: 4885860
    Abstract: A yard sign having two display panels, each of pan shaped configuration and adapted to nest one within the other so that a cavity is formed therebetween. An H-shaped support frame is positioned within the nested panels with only that portion of the frame's legs that extend below the frames's crossbar being located exteriorly of the display panels. The top edges of the H-frame's legs abut the nested display panels' top edge to prevent the display panels from sliding down on the support frame, and the support frame's crossbar abuts the nested display panel's bottom edge to prevent the pans from sliding up on the support frame. The legs are spaced apart one from the other a distance sufficient to minimize twisting of the display panels on the support frame relative to the sign's vertical center axis.
