This is a roccoco painting hanging in the Art Insitute. In English, the title reads "Are they thinking about the grape?"
The answer, one supposes, is 'no'.
I'm drawn to the color, the expressiveness of the trees, and the intensity of the boy's stare. The limbs of the children form a pleasant circle that draws our attention both to the grape and to the space between them, neatly delineating the governing question of the painting.
