Children playing, amateurs rehearsing, music outdoors, and Schubert himself at the piano: paintings by Manet, Degas, Thomas Eakins, Édouard Vuillard and others.

Mud as painted in the Danish countryside, and in Norway. But the last word goes to war: both in the Franco-Prussian and First World Wars.
Religious works, including two Nativities and a fine painting of Joseph and Mary walking to Bethlehem, Naturalist and Impressionist styles too.
A major German painter in the late 19th century, he is often claimed to have been an Impressionist, but these works look very Naturalist to me.
