Portieux? Set of 10 cut glass champagne flutes from 1900 bistro.

This superb set of 10 antique champagne flutes is made of cut glass. It is a beautiful 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 have been 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 16.8 cm in height X 5.7 cm in diameter. One glass measures 17.5 cm X 5 cm in diameter. There are signs of use and only one glass has a chip.
