The Major Peirsons Death(1782-84) John Singleton Copley (1738-1815)

The picture has something of this: people, man, lithograph, group, crowd, cavalry, many, army, woman, transportation system, uniform, soldier, group together, music, war.
Perhaps it’s a painting of a group of men and women in military garb, with a flag in the foreground, and a building in the background.
