Calligraphy (reverse), 1800s. This screen depicts paintings on one side and poems on the other-an economical format often used in Korea to allow the viewer to enjoy both sides of one screen. The front features an assortment of bird-and-flower, landscape, and figural album leaf format paintings executed according to the brush manner of more than 50 artists.
