The 'functional style' of the 50s found its clearest expression in the model FSB 1020. Johannes Potente designed this model in 1953. His design’s strong points are its physical dynamism, its simple hand shape and an assymmetry that gives the illusion of symmetry. When Johannes Potente designed his 1020 model, it was his intention to provide visual relief from the strict lines of the door, 'inviting' the observer to take hold of the handle. FSB 1020 is one of four models designed by Designer Johannes Potente which became part of the permanent collection of the MoMA in New York.
