In this portrait, Seo Mae-su is depicted wearing an official hat, a waist belt, and a dark green ceremonial robe with a rank badge embroidered with a twin crane design attached to its front. This is typical of the full stature portraits of a government official dressed in an official robe produced at the end of the 18th century. The portrait features realistic descriptions of natural facial expressions achieved by detailed brush strokes, and a bold use of light and shade to express the robe’s creases.
