The image shows a portrait of a man from the chest upwards. He has short, neatly combed hair with a light wave. His facial features include distinct brows, a pointed nose, and a subtle mustache. He is wearing a dark coat over a high-collared white shirt with a loosely tied cravat. There are no visible accessories or objects in his hands. The background is a plain, graduated shadow that enhances focus on the subject. The name "John Forbes Mitchell Esq." is written at the bottom of the image, along with a mention of "Thainston, Aberdeenshire."
