Ludovico Sforza 4810: Montblanc limited series from the Mécènes collection, from 2013, paying tribute to the Duke of Milan, Ludovico Sforza, Leonardo da Vinci's patron. Numbered 4199 out of 4810 pieces. Made in high-gloss black lacquer and decorated with silver inlays, it pays tribute in every detail to the Duke of Milan and his court artist, Leonardo da Vinci. As for the cap ring, it recalls the testone, one of the Italian Renaissance silver coins minted in honor of Ludovico Sforza. The design of the top of the cap and cone reflects the pronounced architecture of Castello Sforzesco. Ornaments from Leonardo da Vinci's ceiling fresco in the Sala delle Asse of Milan Castle embellish the ring of this writing instrument. The engravings on the rhodium-plated 18-carat gold nib are inspired by the Sforza coat of arms. Piston filling. In its wooden case with papers and over-box.
