It's a stunning period piece, the kind of thing you can imagine in some hip and stylish home of the day. I've already got a back story in my head of a space age hangout for an Italian film director!
The seller says it is attributed to Fontana Arte, built around a chrome frame with 76 thick chiseled crystal glass segments. it has apparently been rewired to modern standards, with the chrome cleaned and in 'very good condition'. Some glass seems to be chipped (close-ups on the listing), but with the chiseled style, it would be hard to spot.
Not cheap at £334.78, but if you are kitting out a room in a luxurious late '60s style, this really would be the perfect finishing touch.
