Abstract
Abstract A portable yard sign adapted for easy storage, transport and assembly, which is simple to install and remove from a soil bed, without special equipment, and which consists of a rigid upright post having a longitudinal slot extending downwardly from its top edge, and a main sign panel having a foldable side edge corresponding to and insertable into the slot for securing the panel to the post, the post having on its bottom end a ground stake and foot plate assembly for penetration into the soil bed upon application of foot pressure thereon. The main panel foldable side edge may be formed by scoring an edge of the panel and cutting tabs along the folded edge, or by connecting a hinged member along an edge of the panel. A modified embodiment of the invention may utilize an inverted L shaped post with the slot for receiving an edge of the sign panel formed in the post leg parallel to the ground and the sign panel hanging from the post leg toward the ground.
