The image is an engraving featuring a man with a long face, pointed beard, mustache, and medium-length curly hair. He wears a broad-brimmed hat with a decorative band, a cape with a high collar, and tassels. The background is plain with a horizontal line across the upper part. Below the portrait is text identifying the person as "Tho: Percy, one of the Conspirators in the Gunpowder Plot," with a small printed note indicating the engraver as Adam. The image is on textured, off-white paper with aging effects like small spots.
