Facsimile of Leonardo Da Vinci's pocket notebook. You can see his classic left-handed reverse writing. The ink has an oxidated brownish look about it, perhaps because he used sepia (cuttlefish) or iron-based inks.

Fascinating to see Da Vinci’s reverse writing up close... such a unique piece of history.
They did a great job with these copies because they maintained the style and general dimensions of the originals.
