Series of 4 Champagne glasses Marne crystal cut 1920 by St. Louis

These four pretty champagne glasses are made of saint-louis cut crystal. This is the marne model of st. Louis: it is cut from flat ribs. Dating back to the 1920s, the leg is short and punctuated by trimmed knots. The drinker has a beautiful flared shape, the crystal reveals an exceptional resonance and superb transparency. In good condition, they measure 7.6 cm in height and 9.8 cm in diameter. I'm reporting discreet shrapnel.
