Maybe not very easy to see what this is… It´s wooden blinds designed by Verner in 1991. Actually it´s his own protype versions for these used in his office at Kohlenberggasse, see the picture with Verner Panton. (Copyright to Panton Design office for that picture). Two of them are purple/violet and one is blue/yellow. (One colour on each side).
Each pair of blinds measure 140 x 250 cm so these three blinds covers an area of 420 x 250 cm.
