Limprudente Elizabeth Jane Gardner (Bouguereau) (1837-1922)

The picture has something of this: woman, people, outdoors, nature, relaxation, water, sit, love, girl, leisure, two, grass, recreation, child, park, young, summer, river, man.
Perhaps it’s a painting of a woman laying on the ground next to a young girl who is holding a baby in her lap, with grass and trees in the background.
