Navajo saddle blanket/rug circa 1920's

My mom found this at a thrift store auction years ago; won it for around $20.oo. We have always loved its pattern and coloring and being curious, I asked an on-line auction house for an evaluation and found out that it is most likely a Navajo saddle blanket from the 1920s. It is almost completely square, with each side measuring about 24 to 25 inches. I love the combination of orange and blue.
