Vtg 1940’s Native American Navajo Rug 28” X 53”

1940’s Native American Navajo Rug 28”X53” I traded for this rug in 1978 from a lady that made it. There is a stain on it and u will c in the pics that some little bit of the weaving has come lose. Please check c pics. The colors are all Natural. Gray, Black, two colors of tan. I am from New Mexico USA and my mother in law was a BIA agent for many many years, so I would go with her to there homes and do some buying and trading often for many years so that’s how I come about this rug and others.
