Business correspondence written on letterhead from the late 19th century. Letterhead includes design with business name and text reading: "Southern Pacific Company, Sunset Ogden & Shasta Routes"; "Most of this Company's freight cars are built to carry twenty to twenty-five tons of weight. Never load less than 12 tons. If shippers load to weight capacity, which is plainly marked on sides of car, it will do much to obviate delay in furnishing cars for loading and prevent detention in transit. Do not load to exceed weight capacity."
