Half-length portrait of a man sitting at a desk in an office. He is looking downward and is holding a pen over a book on the desk in front of him. He is wearing glasses, a suit jacket and vest, a collared shirt, and a tie. The name “Mack, Dr.” and the text “Milk Dept, City Hall” are written on the negative sleeve. The man is probably Dr. D. W. Mack, a veterinarian and milk inspector for the city of Portland.
