DSP. Maker marked "Reliance Advertising Company." A nice example of this double-sided porcelain sign from Standard Oil, featuring good colors and graphics. CONDITION: Side one retains good color in the field. There have been areas of restoration performed mostly in the center field and also towards the outer edges of the sign. (7.0). Side two shows porcelain loss to the center graphics and fading throughout the colors. Outer edges show wear, surface scratches and porcelain loss. (6.0).
