Our Picnic, New Lock, Berkshire Charles James Lewis (1830-1892)

The picture has something of this: tree, fall, park, wood, leaf, landscape, people, girl, picnic, garden, light, nature, woman, outdoors, lake, man, recreation, dawn, daylight.
Perhaps it’s a painting of a group of people sitting at a picnic table in a wooded area with a river in the background and trees in the foreground.
