Rare table lamp base Maison Le Dauphin 1960-70

Rare model of lamp from maison le dauphin dated from the 1960s-70s given the materials used and the original fittings). This is the "lizane" model; made of molded glass with art-deco decoration (no identification of the verrier manufacturer) the original label is under the base and perfectly identifies the model. In addition, I think that this lamp base has never been used and is a store bottom because a label is still attached to the cable and indicates the model and the price in belgian francs (for the record, the price of 3700 fb indicated would represent approximately 400 euros today, this clearly indicates that this item was indeed high-end at the time...). There are traces of oxidation on the gold metal plate covering the glass base. E27 socket. Original wiring and switch in perfect condition. Good condition of the glass without dents, chips or cracks. Weight 1.5 kg - max diameter: 14 cm - total height with the socket: 29cm -- height without the socket: 23 cm. There are many images because it is not easy to photograph a glass object with its details. I illuminated from the back so that the patterns can be clearly seen.
