vintage Asian/oriental quilted embroidered duvet/throw/blanket

This stunning quilted duvet is in royal blue and red with 5 embroidered medallions with 2 white and black birds in the center of each. The measurements indicate it is smaller than a twin duvet. More like a throw size. It has a zip opening with a Taiwan stamped zipper pull. The only tag is shown says Zion with Z in a circle. Unable to find out anything about it. Unsure of the fabric content although I would guess silk. It is Asian but no idea if it's Japanese, Chinese or other. The red center is more finely quilted than the royal blue boarder. It has orange stitching. It measures 74" L X 44" W X 1 1/4" D. I believe it is from the 1970's or 80's. It is in like new condition, no fading, stains or wear. It looks like it has been safely stored for decades. It is too small for a twin bead but can be used at the end of a bed. Shown at the end of my king size bed. Over a sofa or chair. I ship same or next business day.
