Circa 1936-1944: The large tall Riviera tumbler with the hand applied handle would have been slip cast in two parts and then joined by a potter, fired once, hand dipped in glaze and fired again. Only produced in four colors of original Mauve Blue, Original Mauve Blue, Harlequin Yellow and Original Red (ivory examples surface occasionally, but are extremely hard to find). This example of the Riveria handled tumbler in the original Mauve Blue is in excellent condition without damage and will be a delight to add to any collection.
