Blue and yellow prototype for the “Luminous Wall Element” made ca 1969. It has been several later made copies around but this is one of two originals still existing.
This panel is attached in a box of mirrors to duplicate the panels when you look inside this box.
The blue and yellow panel was the prototype for what Verner Panton later used in his legendary Visiona 2 exhibition when he covered a room in super cool green / light green panels. Some of them where lit up from behind and some where attached on the walls and ceiling without light.
