This inkwell, designed and cast by Tiffany & Co. of New York, was presented to President Lincoln in early 1865 by Charles D. Poston, the first delegate from the Arizona Territory to serve in Congress. Made from more than 400 ounces of Arizona silver, the calling bell in the center represents the newly completed dome of the United States Capitol. The bell is flanked by finely executed representations of a Comanche Indian and a pioneer.
