Verner Panton designed the Ball lamp and the Spiral lamp and in 1970.
The were made by the Swiss company Lüber and were sold during the 70:ies.
I have now learned that they produced between 300-500 pieces of the Ball lamps during this period.
50 pieces of these were made in the biggest size with large balls. You can see one of the bigger models above.
Also, The Spiral lamps were made in between 500-1000 pieces.
Most of the Spiral lamps were made in chrome.
So I guess there are some of these lamps here and there.
If you have any you would like to sell, I would be interested in buying it for good money!
