View of U.S. Marines in jeep crossing bridge on Guadalcanal during World War II. Typed on back: "File no. W-SOL-17-13292. Displaying typical Yankee ingenuity, U.S. Marines used amphibian tractors (lower left) to provide the foundations for a bridge over a stream on Guadalcanal. The structure obviously is serving the purpose for the Devildogs at the wheel of their 'jeeps.' Official photograph. Please credit U.S. Marine Corps." Handwritten on back: "Jeeps."
