The image shows a portrait of a person in an oval frame. The person is depicted from the chest up in a slightly turned position facing the right. His facial features include a long, straight nose, a prominent mustache, and wavy shoulder-length hair with curls at the ends. The individual is dressed in what appears to be a military or formal garment with riveted metal pieces, possibly armor, and a high, lace-trimmed collar. The background consists of closely spaced lines creating a textured backdrop. An inscription below the portrait reads "Robertus Duguay" with additional text in Latin.
