Art nouveau lamp in glass paste signed tief

This sublime table lamp is composed of a glass paste base and a thick globe in marbled glass paste and signed tief. In the art nouveau style, this lamp takes up the natural forms of this famous style: mushroom-shaped, it is a marbled glass in shades of green and orange. It is a reissue by the French decoration house tief, inspired by the school of nancy, made by the thieffry family in the 1970s-80s. The signature is engraved "tief". It measures 48 cm in height and 19.5 cm in diameter. I report scratches from use.
