Space Age wall lamp / art piece by Studio EF, Italy 1970's

Unique sculptural wall art incorporating three lights in Space Age design language by Studio EF Viareggio, Italy.
 
Nine chrome plated metal spheres mounted on a black wooden panel with satin gloss black finish. Three mirror bulbs in the top half complete this rare and interesting mid century modern piece. Spectacular light effect on the surrounding surface and the chrome spheres!
Signed in the right corner "P. Stell" (as read by us) plus the producer sticker "Studio EF Viareggio" in verso. Limited production, prove of authenticity.
 
In very good vintage condition. Two spheres have some chrome flaking on the side. Including 3 traditional mirror bulbs.
