Montblanc, the brand of sophisticated accessories, has unveiled a film about the creation of 2013 year’s limited-edition “Patron of Arts” fountain pen. Every year since 1992, the brand releases limited-edition luxury pens to triumph the philanthropists of the past who supported art. This year’s piece is devoted to Ludovico Sforza, the Renaissance ruler and patron, who supported painters, artists, architects and men of letters, including Leonardo Da Vinci and architect Donato Bramante.
