The image displays a portrait of a man from the chest up. He is posed in a slight three-quarter view with his head turned forward but slightly to his right. He has a serious expression, pronounced cheekbones, and a relatively thin and straight mouth. His hair is wavy and of medium length, extending down to his shoulders. The man is dressed in a formal suit of armor that appears to be of historical significance, with a high, white, pleated collar peeking out above the armor. The background is plain, with a stippled pattern texture. At the lower part of the image, there is an inscription identifying him as Oliver Cromwell, detailing his titles and roles, alongside credits for the artwork.
