This glass has a pattern of “Edo Kiriko”, but once you turn the bottoms upside down, you can see the patterns as a doll. We took in the techniques of hidden pictures. In Japan, we have the culture of decorating the house with dolls in March 3rd, for celebrating women. Formerly, people decorated the house with vassal dolls in addition to king and queen dolls, but people only decorate the house with only king and queen dolls, nowadays. This doll glass can be used to drink alcohol for ordinary use as well. This was a collaboration project with an “Edo Kiriko” craftsman in Tokyo.
