Codex Vallardi
The Codex Vallardi is a collection of drawings by Antonio Pisanello, acquired for the Cabinet des Dessins of the Louvre for 35,000 gold francs from the Milanese print dealer and antiquarian Giuseppe Vallardi in March 1856. Consisting of 378 folios, its purchase was negotiated by Frédéric Reiset, who also reinstated its correct attribution, replacing a misattribution to Leonardo da Vinci.
