Realism was an artistic movement that emerged in France in the 1840s, around the 1848 Revolution. Realism revolted against the exotic subject matter and the exaggerated emotionalism and drama of the Romantic movement. Instead, it sought to portray real and typical contemporary people and situations with truth and accuracy, and not avoiding unpleasant or sordid aspects of life. The movement aimed to focus on unidealized subjects and events that were previously rejected in art work. Realist works depicted people of all classes in situations that arise in ordinary life, and often reflected the changes brought by the Industrial and Commercial Revolutions.

From here it seems to be an old painting and of course I think it is valuable
