Portret van Sophia van Wurtemberg, koningin der Nederlanden before 1878

This is a portrait of Sophia Frederika Matilda, Queen of the Netherlands, an anonymous photograph from before 1878. This small format portrait is a carte de visite, a popular form of photographic portrait during the 19th century, and was likely part of a publication, as it is seen pasted into an 1878 edition of the *Cadetten-Almanak*. The photograph is housed in the Rijksmuseum in Amsterdam, a major Dutch museum dedicated to Dutch art, history, and culture.
