Take six brands: Braun, Citroën, Herman Miller, Olivetti, Sony Swiss Air and study all their brand communication. A Gem from 1975 with some great work in it. Here are a few Braun elements. I find it hard to draw a parallel with the Braun identity of today, but something tells me that if the work was as minimal as it was in 1975, it would seem like a much more luxury brand.
