Set of 6 champagne flutes called 'trinquette' or 'cul sec' in mouth-blown glass, vintage

Here is an adorable set of original champagne flutes and for good reason: they have no foot and can not be installed in a classic way. This type of glass, well known in french festivities, is called trinquette (or ass -dry in the regional jargon of my country): it was a question of having to drink its contents to be able to rest it. If we have come across very common ones, distributed by wine dealers, or very chic crystal, these were blown in the mouth, artisanally in the 70s! They bear the irregularities that can have the artisanal creations but have no lack, crack, chip. They will accompany your strongest moments by accompanying the festive bubbles. Height 20 cm. Diameter 8.5 cm.
