Emile Gallé - Art nouveau vase "Aux volubilis"

Superb doubled crystal vase, with a large bulbous flat base and a long faceted blown neck.
Fire-polished proof, finely engraved decoration in acid cameo of mauve volubilis on a turquoise background with intercalary coulures.
Nice signature on the wheel "Cristallerie d'Emile Gallé à Nancy modèle déposé".
