Framed Cover of The Saturday Evening Post, Nov. 23, 1918, Featuring Trench Warfare Scene of American Red Cross Service Dog in World War I

A poignant illustration by Charles Livingston Bull, well-known for the illustrations he provided for several of Jack London's works (most notably The Call of the Wild). An American Red Cross service dog is pictured holding a helmet in its mouth, ostensibly belonging to a soldier wounded in the trenches and in need of medical assistance. Barbed wire stretches across the background.
