The description states:
K103–NAVAJO INDIANS AND THEIR HOGAN
These Indians and their Hogan are very typical of those seen on the Reservation today. They derive their living from cattle and sheep. Their Navajo Rugs and Navajo Silver Jewelry is very much in demand. The Hogans, the Navajo’s homes, are made either of wood or rocks in aboriginal style.
–The older style of hogan construction was essentially extinct by this time, having been replaced by significantly more substantial and geometric structures like the one shown here.
This postcard likely dates from the 1950s.
