In the 1800's, Pure Nacional chocolate was synonymous with fine chocolate and was the dominant fine chocolate of its day. Latin American cacao trees were struck by diseases in 1916. Within three years, 95% were destroyed. This fine chocolate was thought be forever LOST.

FOUND. Then in 2007, Dan Pearson and Brian Horsley stumbled upon trees with large football-shaped fruit pods in a remote Marañón Canyon in the Peruvian Nacional Valley. Many pods contained 40% white and 60% purple beans, and in some, 100% white beans. In short, these pods contained the rarest cacao beans in the world, as the Pure Nacional, and was named Fortunato No.4. 

The simple, yet clever, packaging emphasizes the sense of discovery. You need both the box and the chocolate bar to make up the name and to recover the missing letter O.
