Navajo Sand Painting of Moon Guardian 1960s

This sand painting is one of a set of three that came from the same estate. One is signed by Navajo Artist Rita Johnson and the previous owner feels that they are all by the same artist. Each has old yellowed paper on the back explaining the content of the painting. 

This one is the Moon Guardian. Framed it measures 6 7/8" by 6". Has a hanger on top that was very in style in the 1960s. Frame is pine. Needs light cleaning. Paper on back has some damage.
