Set of 5 octagonal copper teacups, a specialty of Hiroshima. They come in a wooden box and are signed by the artist. It appears they were purchased at Fukuya, a long-established department store in Hiroshima. These were found during the clearing out of my parents' house. I'm not sure if they were purchased or received as a gift, but they have never been used. I hope someone will be able to use them.
