Antique Liquor Glass Basque A

I believe these are glasses made by Portieux.

These are charming hand-blown liqueur glasses with a Basque pattern. They would look lovely paired with our antique tableware Basque pattern series.

Condition: No noticeable scratches. Due to being hand-blown, there is some slight distortion.
Size: Diameter 4.5cm x Height 7cm; Capacity when full: 80mL
Era: I believe they date from the early to mid-20th century.
