Circa 1938-1940: 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, "Mauve" 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. This example in the wonderful vintage Harlequin Blue is in excellent condition without damage or signs of use, a great even glaze without flaws and a nice rich colored "Dripcut" lid.
