This is a phenomenally rare buffalo horn headdress war bonnet with hair roach and beadwork from the Crow Native American Indians of Montana from the late 19th Century. The war bonnet shows a porcupine quill hair roach at the top with polychrome painted parfleche, hide bonnet cap and is further adorned with harness saddle leather, a glass trade seed beaded brow band, and Buffalo Bison horns. The brow band is constructed of a harness leather with trade thread sewn glass trade seed and petit beads in a floral pattern in colors of greasy yellow, red white hearts, greasy green, Cheyenne pink, cobalt, rose, and dark red. The Buffalo Bison horns are trimmed in white fur caps and drops of Upland game (likely Sharp-Tailed Grouse) benches of feathers tied with trade cloth in a red dye, hawk trade brass bells, and horsetail hair. The skull cap also shows a green geometric pattern painted on and the hair roach has a woven green center. This is truly an unusual and rare piece. Provenance: From a historic Eastern Montana American Indian Collection, where the piece was found to be an authentic original, one of the finest collections of American Indian weaponry and antiquities in Montana. The headdress is 17”W by 15”D with an inside circumference of approximately 22”.
