Vintage Hand Embroidered Cotton-Linen Summer Thin Coverlet

A vintage embroidered thin summer coverlet or sheet, in a cotton most likely blended with some linen. This has a bit more texture than most cotton, but is still a thin fabric, like a sheet. I believe it is intended as a summer cover, though, since there is embroidery of the monograms on the top where the pillows go, rather than on the opposite side where you would turn down a sheet. It is quite large, 103 inches by 105 inches; it is shown on a queen size bed. There are two seams running down the length of the piece; nicely done, but definitely by hand, as they are not perfectly aligned with the R's. A great deal of hand work went into this piece. It is in very good vintage condition. There are a few tiny dark specks near the top on the right, and a random pink thread in the piece that has nothing to do with the embroidery. There are a couple of yellowish areas in the center, which I think will go away with washing; they are not easy to see. I have not washed this piece.
