Circa 1959-1969: The Fiesta medium green oval platter is rather uncommon because it was only manufactured in the last ten years of the dinnerware line's production. Note that the original vintage medium green Fiestaware platter, like the platters in the four 1950s glazes, will always be 12.5" in length because the size of the platter was dropped 1/4" in 1947, probably due to difficulties with warpage during the firing process.
