This image shows an extended Navajo family in front of a typical domicile wearing clothes common for the 20th Century, and for the women, for some time before.
The description states:
14–NAVAHO INDIANS AT HOME
The Navajo Indians, 50,000 in number, show little influence of the advance of civilization, living by the primitive methods of their forefathers. Many of them live in such remote districts far from civilization that they seldom see a white man.
Their hand made blankets, of wool from the sheep raised by them are known for their unexcelled quality and design throughout the world. Their hand made jewelry is as much sought for.
–This image likely dates from the 1940s.
