Circa 1960-1965: The The HLCCA (Homer Laughlin Collectors Club Association) Fiesta, Harlequin and Kitchen Kraft Dinnerwares guide makes note that Harlequin medium green is considered "scarce, very scarce, and rare". It is true and finding any medium green Harlequin is a feat. The modest 6" bread and butter plate is considered very scarce in medium green. This example is spectacular, without a sign of use. Measures 6 1/4" wide by 5/8" tall. Unmarked as all original vintage Harlequin was.
