Pair of pillowcases in old linen in early 1900

Pair of pillowcases in linen in early 1900 monogrammed, embroidered richelieu and adorned with days of different kinds. Closure with mother-of-pearl buttons. There are one or two rust spots the size of a pinhead. There is a specific product in hypermarket to remove them permanently. This type of pillowcases of this quality becomes from 'in' to 'hard to find'. Feel free to dye them if you like it gives a very beautiful rendering. I would put it on sale soon in shades of light gray and anthracite gray. Dimensions; 75 cm X 75 cm, cushions of this size can be found on the internet in 80 cm X 80 cm.
