 Albumen print, business card format
 Charles de Bourbon (1848-1909) is known as Don Carlos. The eldest of the Capetians and head of the House of Bourbon, he claimed the throne of Spain under the name "Charles VII".
 Political and military instability allowed him to establish himself in Navarre where he was proclaimed King of Spain until 1876 when he fled to France.
 After a brief stay in France, he traveled to the United States and Mexico. Upon his return to Europe, he settled in Paris, but was expelled in the 1880s following the implementation of the law of exile against pretenders to the throne of France, and eventually settled in Venice.
 Augustin Aimé Joseph LE JEUNE was a Parisian photographer, established on rue St Honoré in 1872, specializing in portraits of Parisian personalities and of His Imperial Prince.
