This is an original Japanese woodblock print by Katsushika Hokusai, titled 'Kōya, the Dyers' Shop at Kanda' (神田紺屋町). Published circa 1805, it is a page from the three-volume illustrated book 'Ehon Sumidagawa ryōgan ichiran' (Illustrated Book of Scenery on Both Banks of the Sumida River). The print features a detailed interior view of a dyer's workshop, showcasing artisans preparing and working with bolts of cloth. The dimensions of the full piece are 10 1/2 x 15 1/2 inches, with the image area measuring 7 1/2 x 11 3/4 inches. Please note the significant water stain in the upper portion affecting the 'sky' area, as well as the overall age-related toning to the paper. Despite these issues, Hokusai's artwork remains a captivating representation of Edo period craftsmanship.
