Set of 6 tarn red wine glasses in cut crystal from saint-louis h16 cm

This superb series of 6 crystal red wine glasses comes from the saint-louis manufacture. They belong to the "tarn" service of saint-louis, this model was created in 1957. It is a large stemmed glass, size no. 3, wine is served in it. The rim is richly cut with diamond and point patterns. They measure approximately 16 cm in height X 7.5 cm in diameter at the rim. In very good condition, I note scratches from use. Some are signed "cristal st-louis france" at the base, clearly visible on one glass and not clearly visible on the others. There are small manufacturing defects on some: discreet bubble or small dot in the crystal.
