Zeroll 24 Red

Perrysburg, Ohio; February 9, 2025
An orange with a metal patent marking plate from a vintage machine attached to it. The label reads "Sunskist" in bold blue letters, indicating the patent marking plate is for a Sunkist brand fruit juice extractor. The marking plate references the extractor being made in the U.S.A., patented in 1917, and that it operated on 110 volts and 50 cycles. The marking plate also references the California Fruit Growers Exchange and provides an address in Chicago, Illinois. The orange is set against a dark background, highlighting its vibrant color. Overall, the scene provides an interesting contrast with the patent marking plate from the extractor maching being directly attached to a fruit, the orange, on which the machine, not visible in the photograph, would have operated.
