Yoshio Hamada Born in Mashiko, Tochigi Prefecture in 1944 (fourth son of Shoji Hamada) Graduated from Tama Art University, Department of Sculpture in 1968 Graduated from the Royal College of Art, Industrial Glass in 1972 Built a kiln in Kanuma City, Tochigi Prefecture in 1973 Held his first solo exhibition at Mitsukoshi, Nihonbashi, Tokyo in 1978. Since then, he has held many solo exhibitions. Died in May 2011 There are two. They are handmade, so they are not identical. Please consider which one you prefer. Regarding ②, subjectively: Slightly smaller than ① (both in diameter and height), but ② has thicker glass than ①, giving it a gentle and weighty impression. I will store and ship them carefully to avoid any mistakes.
