Reto Holzer Coiffeurs, Zurich, Switzerland

When Keller Maurer Design refreshed the RHC identity, the minerals moved from supporting motif to subject. This second series leaves out portraits and interiors entirely and stays with the stones: agate cross-sections, geode slices and quartz, photographed as flat graphic surfaces whose banding and colour carry the brand on their own. The earlier commission for the salon is here.
