This glass pendant light is documented in a catalogue by the company of 'Indoor'. This was the importer and dealer of light brands as Vistosi, Venini and Arteluce in The Netherlands. They do not connect this light to a designer or producer in the catalogue of 1967. But most likely it is Italian and by Venini or Vistosi. This lamp is in a very good condition and gives a beautiful light. We also have a green version of this lamp available with a photo of documentation.
