At our art museum last evening, Tousui Tanaka an internationally acclaimed Japanese sumi-e (black ink painting) and calligraphy artist gave a wonderful lecture and demonstration. She does traditional and contemporary work. This picture shows her demonstrating her painting technique on paper with black ink and her natural bristle brushes.
She demonstrated 5 different styles of Japanese calligraphy, all of the above papers spell "moon". Some are very ancient styles.
