Portieux? Meisenthal? Set of 10 cut glass champagne flutes with flat sides from 1900.

This superb set of 10 antique champagne flutes is made of cut glass. It is a collection of stemmed glasses made from mouth-blown glass with flat cut facets. This is an old production from the 1900s, probably from the factories of Portieux or Vallerysthal (common catalogues from the 19th and early 20th centuries) or Meisenthal. These glasses were mouth-blown; they show bubbles in the glass and the mark of the cane is visible and has been cut. These champagne glasses date from the turn of the 20th century. They are in generally good condition; they measure approximately 17 cm in height X 6 cm in diameter. I note some signs of use and scratches.
