Saint-Louis set of 6 antique glasses with acid-etched rocaille and flower decoration 1920-30

This superb set of 6 antique stemmed glasses is made of acid-etched crystal, probably from Saint-Louis. The decoration is elegant: the glasses are adorned with rocaille friezes and delicate flowers in chemical engraving. Typical of the early 20th century, it is a model close to the Talma service from Saint-Louis (engraving 899 in the 1930 catalog). In beautiful condition, they measure 13.3 cm in height X 6.5 cm in diameter. Note: scratches from use.
