Elegant sculptural crystal vase by Daum, produced in the Nancy factory and signed “Daum Nancy France” with the Cross of Lorraine, the historical emblem of the Daum glassworks. This piece belongs to Daum’s mid-20th-century modernist production, characterized by heavy clear crystal, the use of controlled bubble inclusions (bulles contrôlées) and bold applied side handles. The signature is hand-engraved on the base in the typical Daum cursive script used during the post-war crystal era.
