Ardalt-Lenwile Zodiac
From Mystic Tea Room
This black and white cup with thick gilding on the black areas is not back-stamped "Japan" or "Made in Japan" but it came with a red and silver foil sticker reading "Hand Painted / Lenwile China / Ardalt / Japan." It is also backstamped in iron-red with the numerical code 6388, which is likely a catalogue number, not a dating code.
Ardalt-Lenwile imported many other examples of gilded black-ware from Japan, but this self reading astrological cup with an unadorned interior is the only known tasseomancy piece attributable to the company.
