Pendleton Indian Design Wool Blanket

I have two of these excellent condition blankets I purchased around 1981 at an estate sale in Paw Paw, MI.  These blankets had been stored by the original owner in a chest along with clothing and dolls. The story was the daughter died at 7 years of age in the 1920's.  The owner put these items in a trunk in a room upstairs in this old farmhouse. They were not opened again until the estate sale. I believe the story because we also purchased a perfect condition dress and doll that was also in the trunk.

Anyway, I have perused the internet looking for this particular design and can not find it. I would appreciate any history behind this blanket and also the approximate value in today's market. I am 62  years of age and am downsizing. These blankets has been in an airtight container with mothballs. They continue to be in excellent condition.

Thank you for any information you can send my way!!!

Good
