1970s vintage camp blanket, Native American Indian style print southwest colors

Never used 1970s vintage 'Indian blanket' print camp blanket. This is a synthetic (polyester?) with printed pattern, not a woven design. It's cheaply made and kind of stiff and scratchy, but it's in excellent condition, still in the original plastic bag in was sold in 40+ years ago! I just opened this up for the photos. Measures about 72" wide x 88" long.
