Pair of antique sheets embroidered Métis Fleur Bleue de Gérardmer

Very beautiful pair of old sheets, top and bottom, Métis model woven in Gérardmer by the company Fleur Bleue at least 60 years ago, with a pretty openwork embroidery. They have never been used, never even washed, I found them still packed (the packaging was a little open on one side and to yield while transporting them). They are made of cotton and linen (pure cotton warp, pure linen weft). They are in their original state, perhaps a very slight coloring or discoloration in places, and again, it is not even safe, the linen being by nature unbleached and slightly lifting the different layers, we do not see any difference in color. According to the label, they measure 220 cm by 310 cm. The set weighs about 3.3 kg.
