"Gevron 1845" noted on the back, either meaning the artist or the woman in the portrait, this is an overly large portrait miniature of an early Victorian era woman in mourning. Further, in the modified mourning period, so more than 1 year after loss of perhaps her husband, or a child, parent. Brown was permitted after the first year, during which only black could be worn as a tradition of mourning. Her somber pose and the inclusion of simple gold chain and her watch and her earrings and tiara also say she's beyond the first year of mourning. An interesting portrait both of this woman and of her position in a traditional mourning period of her time. Housed in a typical French frame, it is possible she was an Englishwoman. Found in France.
Very good to excellent condition, you can see her out of frame, what looks like disruption to the left of her arm is actually the fabric of the settee upon which she sits. No chips, no cracks. The wafer is 4" x 3 3/4" which is larger than most of the era. Original convex glass, and the frame is in very nice condition and is nearly 7" x 6". Napoleon III was not quite yet in his reign, which began 3 years later. Queen Victoria, c.1837 coronation, was a fashion influencer at this time.
