The classic shape of vintage French Bistro glasses. These delightful glasses date from the second quarter of the 1900s. BVB is the manufacturing mark of the historical French company 'Verriere Beauce-Bourgogne', whose parent company is Saint Gobain. The BVB mark was used from 1934 until about 1945 when the Verriere Beauce-Bourgogne glassworks in La Chapelle-Saint-Mesmin developed and produced the well know Duralex brand. Some of these glasses bear the BVB brand and some bear the Duralex brand.
