[Kōchō gafu
A Japanese woodblock picture book by Ueda Kōchō, published in 1834 and held by the Smithsonian Libraries, probably made for artists and students copying bird, plant and animal forms. The first page spread shows ducks in flight, a hawk on a branch, a leaping fish and a leaf in sparse ink line with light colour, suggesting quick, economical drawing that a designer could borrow for natural motifs. The second shows a boy in a blue robe leading a horse through shallow water with rippled lines, a simple wash-and-line approach useful for compact figure studies.
