Hand painted antique miniature portrait. The piece is painted on ivory and framed in a blonde tortoise shell frame. The portrait is of Ernestina Maria d`Estes. I have done a little research on her and I think she married into the Austrian royals. Maria Ernestina d'Este was born on 12 February 1741. She was the daughter of Francesco III d'Este, Duca di Modena and Charlotte Aglaé d'Orléans. She died on 4 August 1774 at age 33. The portrait is signed but I cannot make out the signature correctly. The painting is beautfilly framed in rare blonde tortoise shell with Boulle (brass inlay). There is a small piece of the tortoise shell absent in the upper right hand corner. It is barely noticeable as the spot has aged with the loss. The frame measures 4 7/8" wide by 5 1/4" long. The piece is also signed on the reverse and numbered. we date the piece circa 1860-80 legal antique.
