Circa 1940-1941: 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. The Harlequin syrup is one of the hardest pieces to find from the entire line and is an absolute joy to add to your collection.
