To keep as it is or to modernize with a new lampshade, the electricity will have to be redone as it doesn't work.
Nice twisted effect of the foot and trapped air bubbles. The body of the lamp has imperfections including chips under the base and another at the bottom as shown in the photos.
The interior has been hollowed out.
Approximate dimensions: total height 36 cm (including 22 cm for the foot with the socket), diameter of the base of the foot 7.5 cm, diameter of the widest shade 24.5 cm.
