Circa 1959: The Harlequin water tumbler was discontinued in 1950 and was only made in the first eight colors. Medium green glaze was developed later and released in 1959. How discontinued shapes appear with later glazes is a mystery, usually answered by custom orders, prototypes or sneaky employees. Whatever the means, advanced collectors will rejoice at a pieced like this, in a non-standard glaze, one of perhaps three known. Measures 4 3/8"h x 3 1/2"w
