The lot features a geometric beaded hide and trade cloth flat bag, referred to as a Signal Mirror bag, attributed to the Crow Native American Indians of the Northern Plains of the Colorado region. The bag is comprised of Indian brain-tanned Great American Bison Buffalo hide, heavy canvas, and old trade cloth. The piece has glass seed and pony beads in a geometric, early style of pattern in colors of white, corn yellow, semi-transparent red, and black and a background of greasy light green with a slight variation in tone. The outside edges are lined in red stroud wool and accented by pony white glass beads. The top strap is a wide Buffalo hide example with trade cloth calico lining showing a bifurcated split tab base on each side, artfully beaded in a geometric pattern, and further adorned with a fancy edge of pony white glass beads, along with Indian hide ties and solid brass hawk trade bells. The bottom edge of the bag has tied on thick Indian tanned Buffalo hide fringes. The pattern is considered a typical Crow diamond and triangular, white-bordered patterns commonly seen on early examples, also can be referred to as a snake pattern. Provenance: From the ex-collection of Cyrus Eaton of London, England. Measures overall 22” L by 7” W.
