Mistress and Servant Félix Édouard Vallotton (1865-1925)

The picture has something of this: people, man, nude, woman, dancing, wear, two, dancer, girl, group, son, love, artistic, recreation, position, child.
Perhaps it’s a painting of two women standing next to each other in front of a body of water with a boat in the distance on the other side of the painting.
