A sign support structure includes a broad base plate having opposed upper and lower faces, and a perimeter edge. Substantially equally spaced-apart openings are formed through the base plate along the perimeter from the upper face to the lower face to receive stakes, respectively, to secure the base plate to the ground. A first elongate support has an upper end and an opposed lower end mounted to the base. The first elongate support extends upwardly from the upper face of the base to the upper end. A second elongate support has an inner end mounted to the first elongate support adjacent to the upper end of the first elongate support and extends laterally outward relative to the first elongate support to an outer end. The second elongate support is adapted to hold a real estate sign.
