Circa 1936-1942: The spruce glaze was one of the original four glazes developed for the Harlequin pottery line, the others being maroon, Harlequin blue (mauve) and harlequin yellow. Discontinued between 1940-1942, collectors will cherish finding such excellent early examples of the harlequin pottery in the original four glazes. This example of the vintage Harlequin 9" nappy in the original spruce glaze is in excellent condition without damage and is a wonderful example. Measures 8 3/4" w x 2 3/4"h
