These wonderful chairs were designed by the famous Dieter Rams. When Vitsoe.com finally obtained the license to remanufacture them they needed to show what the many colour combinations & modular design would look like. Before they had been made. Something I do a lot, photographing things that don’t exist.
The chairs were designed in the 1960’s so there were no computer models: I created new models using the original engineering blueprints. I'm gradually getting more & more into CAD
And the system's modular. You can make a sofa as long as you want.
