The source is Shin Yun-bok's late-Joseon genre painting Seonyudo (Boating Excursion): a small boat on a river beneath an ink-wash cliff, carrying noblemen in black horsehair hats, gisaeng entertainers, a flute player and servants poling and touching the water. A short poem and a red seal sit in the upper right corner of the sheet.
