Portrait of Yamapi, a trusted Ute emissary and runner for Chief Ouray, taken by renowned photographer William Henry Jackson of Denver, Colorado. The cabinet card presents a studio view of Yamapi wearing a woven vest and beaded necklace, his hair styled in traditional fashion with a wrapped braid draped over his shoulder. A peace medal is suspended from his neck, signaling his diplomatic standing, and he gazes slightly to the side with calm composure. W. H. Jackson was among the most influential 19th-century photographers of the American West. His portraits of Ute leaders and allies serve as vital documentary records of intertribal diplomacy and Indigenous resistance during a period of immense cultural upheaval. The title printed along the lower margin reads: “A Runner for Chief Ouray, 4204.” The reverse bears the stamp of the W. H. Jackson Photograph and Publishing Co., Denver.
