This image shows two Zuni women dressed in traditional Zuni clothing holding ollas, a kind of Zuni pottery. They are known not only for the pottery, but there is also a dance troupe of Zuni women who use the ollas during their performances.
The caption states: Zuni Pueblo Indian maidens with pottery ollas near Gallup, New Mexico, F1625
The postcard likely dates from the 1940s.
