These are tea bowls collected by my mother. The work is inscribed with "Seventy-Two Old Man, Chinkei-zo." On the inside of the lid of the box, Tozan Yamada praises the appearance of the finished work and writes that it is a masterpiece of his later years. Since they are both artists of Tokoname ware, we can see that they had a relationship, and it makes me feel a little warm. Please take a look at the photos and if you understand, thank you. ■Size Diameter: Approximately 12 cm, Height: Approximately 7 cm
