Portrait of Young Delisle Félix Édouard Vallotton (1865-1925)

The picture has something of this: lid, people, child, wear, man, boy, summer, portrait, recreation, vintage, outdoors, street, leisure, retro, fun, nature, fashion.
Perhaps it’s a painting of a man in a blue suit and hat with his hands on his hips, standing on a path with a building in the background.
