This vintage East Asian landscape painting depicts a waterfall cascading down mountains, a gnarled pine tree, and birds in flight, rendered in a watercolor or ink wash style with grey, blue, brown, and green tones. It features a red artist's seal and black calligraphy in the lower left. The artwork is housed in a black frame with an off-white mat. The frame shows minor wear, and the back has a brown paper covering with a wire hanger.
