This image shows a Native American from the Pueblo nation dressed in traditional clothing.
The description states:
Pueblo Indians are colorful dressers during ceremonials and fiestas. Each Pueblo clings to the old traditions and religious customs of their forefathers. Taos Indian pictured is in winter dress. In summer white blankets are worn.
–While it is unlikely that blankets would be used in the heat of the desert summer, the color of the blankets would have a potentially positive effect on heat dispersion, as white is less likely to absorb heat from the sun.
This image likely dates from the 1950s.
