Unused, unwashed, bed sheet weight , I believe to be all cotton but it could be a cotton blend . One soiled fold line , vertical and horizontal , as the piece was folded and stored (see photo with fingers) it runs about a quarter of the way in near the top right in the piece .- as far down as the photo with thumb. The colors and tree design look like 70’s, sun and flying birds look like 80’s design - this the deduction that it is late 70’s to 80’s era. I have one more piece of this if you need more for a project.
