4 amber bubbled blown glass cups

4 lovely antique blown glass bowls in a warm amber shade. Each piece is punctuated with small bubbles in the material, characteristic of mouth blowing, which give it all its authenticity. We also notice a trace of pontil under each foot, a signature of artisanal work. Period estimate: 1960s-1970s material: blown glass dimensions: h 12 cm X diameter 10 cm condition: very good vintage condition, no chips.
