Roosevelt was famous throughout his career as a hunter and outdoorsman. Not only was he a fine marksman and hunter who donated hundreds of animal skins to the Smithsonian Institution and the American Museum of Natural History, he was also an author who penned many articles and several books about the outdoor life.
Shown here is one of his well-known books, Ranch Life and Hunting Trail (New York: Century Co., 1896), with 94 illustrations by his friend, the great American artist, Frederic Remington.
The Squair Collection includes all of Roosevelt's books in first editions and in most later editions as well.
The illustration is presumably of TR.
