Ceiling Lamp by Yasha Heifetz for Rotaflex, 1960s

Fantastic and actually very rare ceiling light by yasha heifetz for rotaflex around 1960 (attributed).
unusual model, yasha used cellulose acetate cords (or rather tubes), here transparent, which were placed on top of each other in a ring and wound around in one go.
inside the lampshade on the broad side there is a plastic panel all around, which creates a grid-like effect on the outside because it has exactly opposite grooves to the outer ones.

completely in original condition.
