Anonyme XVIIème - "Portrait de la Grande Mademoiselle" - Musée des beaux arts d'Auxerre

So-called Portrait of Anne Marie Louise d'Orléans, La Grande Mademoiselle (1627-1693), but is probably a depiction of Maria Francisca of Savoy, Queen of Portugal (1646-1683).
Identification proposed by user Ecummenic (talk) based on the comparison with a portrait of Francisca of Savoy (see image below) and the lack of physical resemblance of the sitter of this portrait to other representations of La Grande Mademoiselle.
