Photographer uncredited. Circa 1870s.

Stereoview portrait of Yellow Bear and his wife posed together among large, weathered rocks and foliage. Yellow Bear wears a light shirt beneath a dark waistcoat, metal armbands, a circular medal, and decorated leggings and moccasins. A pouch with a large circular design rests against the blanket drawn across his lap. His wife stands closely beside him, wearing a patterned blouse and a checked blanket about her shoulders.

The reverse bears a pencil identification, "Yellow Bear & wife—Arapahoes," with a further notation, "Okmulkee Conference / Indian Territory." An ink inscription along the edge repeats the tribal identification. The annotations associate the portrait with the intertribal gathering at Okmulgee.

Yellow Bear was a Southern Arapaho chief who, alongside Little Raven, signed the Medicine Lodge Treaty of 1867. The agreement called for the Cheyenne and Arapaho to make their permanent home on a reservation, with federal promises of protection, supplies, schools, and medical care, while retaining rights to hunt buffalo beyond its boundaries. In 1873, he traveled to Washington and signed a further agreement concerning Arapaho lands, though Congress never ratified it. John K. Hillers photographed him at Okmulgee in May 1875, placing him at the same location named in the inscription on this portrait of Yellow Bear and his wife.
