Circa 1959-1960: 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 11" oval platter is considered very scarce and difficult to find in medium green. Unmarked as all original vintage Harlequin was.
