One of the most magical moments in antique map collecting is holding a 330-year-old sheet up to the light and watching history appear.

This is a 1695 copper engraving by Nicolas de Fer, royal cartographer to Louis XIV and Philip V of Spain — and when backlit, the laid paper reveals a genuine Bourbon royal watermark: the fleur-de-lis crown, pressed into the paper at the moment of manufacture in a 17th century French royal mill.

This isn’t ink. This isn’t printing. This is the paper itself, bearing the mark of the French crown — a silent authentication that has survived 330 years completely intact.

Nicolas de Fer was one of the most prolific and celebrated cartographers of the Sun King’s era. His maps decorated the walls of Versailles and were collected by European nobility. This particular sheet covers the strategic coastal regions of Île de Ré and Toulon — both critical French naval strongholds under Louis XIV.

The watermark visible in backlighting is not decorative — it is proof of origin, proof of age, and proof that this paper was manufactured exclusively for official royal publications.

Happy to answer any questions about authentication, the de Fer workshop, or 17th century French cartography.
