Dimitri Bruni and Manuel Krebs form the swiss graphic designer duo Norm. They’re well known for their typeface «Simple» which first got used in their book «The Things». Later, Ruedi Baur of Integral, Paris, asked them to redesign the typeface for use in the new corporate design of the Cologne-Bonn Airport - this version is named «Simple-Airport».
