Gasoline has been a staple of the American economy since John D. Rockefeller discovered the value of the substance in the early 1900s. At first, it was merely the highly flammable runoff from refining kerosene, all of which went completely to waste, soaking into the ground surrounding his refineries. Once the internal combustion engine was invented, Rockefeller realized the immense value of gasoline, and began constructing service stations across the country to deliver Standard Oil gasoline to the drivers of horseless carriages. This Modern Made Standard Oil White Crown Gasoline Enamel On Steel Advertising Pump Plate Sign is in Very Good Condition, with moderate scattered chipping and patina around the front and back corners and edges to give the appearance of age, and with some scattered contrived wear evident. Most interestingly, it’s one-sided, measures 15” x 12”, and boasts “STANDARD / WHITE CROWN” in blue trimmed red lettering at the upper front, the classic “STANDARD” red, white, and blue “torch” logo at the lower front, and “A STANDARD OIL COMPANY PRODUCT” in blue lettering across the bottom front, along with the replica date “1954” at the bottom front left corner. A fine example of a Modern Made Standard Oil White Crown Gasoline Enamel On Steel Advertising Pump Plate Sign.
