Circa 1938-1940: Designed by Fredick Rhead for Woolworths, Harlequin Pottery is a wonderfully inspired American pottery from the late 1930s. Harlequin syrups were produced for as little as 18 months and are extremely hard to find in any color. It is found only in yellow, blue, spruce and red. Examples should have the drip-cut lid, as this one does, and will stand nearly 6" tall by 3 1/2" wide.
