Thank you very much for viewing this item on Mercari. This item is an antique collection piece, a hammered copper three-tomoe family crest decorative object, approximately 14 cm in diameter. I believe this item was used as a cover for a mansion during the Meiji to Showa periods. Please note that the thickness is between 2 cm and 3 cm. I hope that those who are interested in this three-tomoe family crest decorative object, as well as the occasional overseas collectors who purchase it, will appreciate its atmosphere as an antique decorative object. Thank you for your consideration. The three-tomoe family crest is a representative family crest, such as that seen on the Akamatsu family crest, which is descended from the Murakami Genji clan, who were also the guardian daimyo of Harima Province.
