Dejeuner sur l'herbe, 1863 by Edouard Manet, Musee d'Orsay, Paris.

Manet in an attempt to liberate art from the confines of literary and academic subjects by placing contemporary figures outside in the open air. He has become associated with the Impressionists because he began to use the same lighter colors. Notice the similarity between this scene and Tissot's Holiday featured here on October 16, 2020.
