Marie Émilie Thérèse de Joly, "Mademoiselle de Choin" (2 August 1670 – 1732) was a French lady-in-waiting, the lover and later the morganatic spouse of Louis, Dauphin of France.
As a morganatic spouse, she was not styled Dauphine of France.
Marie Émilie de Joly de Choin died in 1732. So whoever painted her is dead for over 70 years, and it is a twodimensional work. So this work is in the publice domain. License: CC-PD-Mark PD-Art (PD-old-100)
