A cartes de visite portrait by Whitney's Gallery, St. Paul, Minnesota, featuring Native American Chippewa Chief Ne-Bah-Quah-Om (Big Dog). This compelling image captures the respected leader who, during the 1862 Dakota uprising in Minnesota, offered himself and his band of warriors to the government to fight against the Sioux. The photograph's historical significance is underscored by the inclusion of a U.S. revenue stamp on the reverse, reflecting its period authenticity.
