Holmes, an American archaeologist, anthropologist, geologist, and artist, in a study setting surrounded by artifacts and books, wearing formal attire typical of the late 19th and early 20th centuries, with a thoughtful expression, incorporating elements that reflect his various professional affiliations and achievements, such as a Smithsonian Institution or United States Geological Survey badge, and a subtle nod to his work on prehistoric Native American cultures and the Holmes Group archaeological culture.
