This painting was made by Mizuno Toshikata 水野年方 (1866-1908) in 1903, a Japanese artist and teacher of Japanese art. This picture shows a beautiful woman sketching (美人の戸外写生), working concentrated. She is wearing a hakama over her kimono. Maybe it is early in the morning, because of the foggy weather. She has a parasol with her, but she does not need it at the moment.
