The Montblanc star emblem was introduced in 1913, and since then, all writing instruments produced by the ‘Simplo Filler Pen Company’ [as the makers were then known] would include the distinctive mark.
“The shape represents the snow-covered peak of Mont Blanc — the highest European mountain, symbolising the brand’s commitment to the highest quality and finest European craftsmanship.”
Quoted from Montblanc’s 100+ year history.
A few years ago, the Montblanc logo was chosen by Creative Review in the top 20 logos of all time. I remember thinking it was a strange decision, mostly because the magazine only showed the logo lockup, which is imbalanced, both in line weight and layout.
But seeing it again more recently, the symbol placement on Montblanc pens, that makes me smile.
