These Mino ceramics were produced exclusively for export in the 1950s. When the bottom of the cup is shone through light, a figure of Japanese woman appears. Back in the day, there were several stamp patterns for these pieces but they deteriorated throughout the years and there is only one left today. At the same time, since there are no longer any artisans who are able to recreate them, it is impossible to produce precisive and photo-like stamps now. Needless to say, when the last existing stamp is worn out, the series will be discontinued permanently. As for these dead stock pieces introduced here, the platform is hand-carved each. By doing so, the pattern is able to gather more light, and the female figure becomes more visible thus making them more highly valued.
