Two Ducks & Iris
The flat-perspective and strong colors of Japanese woodcuts, especially those of Katsushika Hokusai, had a strong effect on Art Nouveau.
Katsushika Hokusai created several series of birds and flowers. The genre is called kachô-e, although it also includes other scenes from nature. Hokusai's kachô-e series included the horizontal oban-sized so-called Large Flower series and the vertical chûban-size, Small Flower series. Published circa 1834.
