This cool Lüber catalogue from 1972 came today as well.
You can there see Spiral and Ball lamps, Fun-lamps, wire furniture and also the Lüber plastic panels amongst other items.
The prices are really interesting. As you see the Fun lamps were more expensive than the Ball and Spiral lamps. Today it is the opposite. The prices are written in the currency D-mark.
I also know from the owner of the company J. Lüber that this catalogue was drawn back. For example there is a stylized picture (not visible here) of the round prototype table I have at Panton World. It never came into production.
