For a discussion of Crow mirror bags see Barbara Loeb, "American Indian Art Magazine," Winter 1980, vol. 6, no. 1, pp. 46-53: "The mirror bag is also a man's bag, and like the bandoleer bag, is more rare than its fame would suggest. Only eighteen and one-half mirror bags in the 1870-1930s style have been located...The earliest record of a mirror bag is in a sketch made by Swiss artist Rudolph Kurz in 1851. In the early days the mirror bag held a large hand mirror with which a man could check his face paint, hair or general appearance."
