The name “Kvikk Lunsj” translates to “Quick Lunch”. It’s the Norwegian equivalent of the Kit Kat bar but with much bolder branding, tied strongly to hiking and other mountainous outdoor activities. (Read much more info about the candy bar on Serious Sweets.)
The striped package design goes back to the beginning of the 75-year-old brand and has become an icon of Norwegian outdoor life, but Helvetica has only been introduced in more recent history (currently paired with Myriad Italic and Gill Sans for smaller supporting type). After seeing older advertisements with other sans serif treatments, one can only imagine how the current design could be strengthened by simply varying the typeface to something slightly more distinctive – perhaps something more Nordic than the eminently Swiss Helvetica?
