RARE Antique Nippon Hand-painted Shaving Mug Floral Japanese

Antique white Nippon shaving mug with handpainted florals and black details. Very good condition with some small manufacturing flaws; small bubble in glaze, painting marks. (See photo) Surprisingly even with the age of this mug there are no chips, cracks, or crazing. 3 3/4" tall x 4 3/4" to the handle. Has a green wreath mark with an M in the center handpainted Nippon mark. This is a very RARE piece. I could only find one other like it for $100.
