This rare chirimen silk mirror cover is a unique piece, measuring 19 inches by 43 inches (48 cm x 109 cm). It features three 'karako' children and a family crest, rendered through yuzen-dyeing with metallic embroidery highlights. The term 'karako' in Japanese art generally refers to small Chinese children depicted in traditional Chinese clothing.

These representations, often appearing as boys, symbolize more than just their appearance. They typically carry connotations of luck, prosperity, and the desire for a male successor who would attain a high social status. They're regarded as benevolent symbols associated with the wish for happiness and prosperity. The 'karako' children are depicted with bare heads except for two small tufts of hair, and their attire reflects Chinese traditional clothing.
