Mid-century vintage 'Indian blankets', a lot of three soft cotton blend blankets in great retro colors. I found no labels on any of them, not sure of the maker(s) or exact fiber content. I'm inclined to believe these are cotton / acrylic rather than cotton / rayon.
These all measure 68" long x 60" to 64" wide. Nice for camping, bunk blankets, or to toss on the porch swing or in the truck!
The green and tan blanket has the most wear of the three, and does show some fraying and thinning spots. The other two show no particular wear, just light use. And the colors on all three of these is very good without fading on either side.
