Portrait of Marshal Bazaine by Appert circa 1870
 Albumen print, business card format.
 François Achille Bazaine (1811–1888) was a Marshal of France, known for his victories in Algeria, Crimea, Italy, and especially Mexico (1863–1867). But he is best remembered for his controversial surrender of Metz in 1870 during the Franco-Prussian War, which earned him a death sentence (commuted to imprisonment), followed by exile and poverty.
 The photographer Appert generally refers to two brothers active in the 19th century: Eugène Appert (1830–1891) and Ernest-Charles Appert (1831–1890). Originally from Châteauroux, they settled in Paris and left their mark on the history of photography with their portraits of political, judicial, and military figures.
