Three phases of a Navajo Chief blanket

Navajo Chiefs Blankets are the most recognizable and valuable of all Navajo weavings. Navajo Chiefs Blankets have been collected not only by other Native Americans before the United States even existed, but also by such notable collectors as William Randolf Hearst.

A Navajo Chiefs Blanket could be purchased for around fifty dollars in the early 1800’s, one thousand dollars by the turn of the nineteenth century, and today, a Chiefs blanket in excellent condition, could sell for half a million dollars or more.
