The two coloured papers in the first pictures above comes from a close co-worker to Verner Panton.
The story tells these papers worked as colour tests when he and Verner developed the aluminium version of the Fun lamps around 1965.
Now I realised these papers were pictured in old photograps from Pantons appartement in 1965. The papers were rolled out on the floor but also attached to the walls next to Verners Mirror Sculpture.
Below you see a close-up picture of a prototype Fun 2 DA lamp: It has painted discs wich worked as reflectors for the light.
