The image shows an engraving of a man, displaying his upper half, seated upright. The man has a long, pointed beard and mustache, with short hair visible beneath a flat, beret-like hat. He is dressed in richly decorated garments, featuring ornate patterns and textures, and holds a pair of gloves in his left hand, with a sword hanging from his waist. His right hand rests on his hip. Around his neck, he wears a frilled collar, and on his left ear is a large earring. The background includes elaborate scrollwork with two cherubs holding a wreath above his head, and Latin inscriptions are woven into the design, identifying this as an image of Thomas Gresham. The portrait is enclosed within an oval frame, with decorative elements and small shields appearing in the corners of the engraved border.
