About the artist: "A pupil of Kitao Shigemasa, and later Kano Yosen’in Korenobu, Masayoshi worked as an ukiyoe artist under the name Kitao Masayoshi. He then became official painter to the daimyo of Tsuyama and worked in the Kano style using the name Kuwagata Keisai... He was a pioneer of a new style of drawing manual called ryakugashiki, which marked an important point in the development of this style of illustration and he strove, in his work, to simplify forms and capture the spirit of the animals he was depicting."
