Library lamp 1900

Office, library or courtroom lamp. Art nouveau period (dating from 1890 to 1919). It is bronze black patina and opaline. The electrical system is period and works perfectly. They are electrified with a bayonet socket and the switch is a small key, attached to the bronze foot. The foot is round, with no visible mark or signature. Only a cross (like a swiss cross) is engraved on the rotating wheel switch, with the words "b.a.g.". At the top, resting on a hollowed-out brass circle, an open cup in white opaline. A real bright jewel!.
