I do love this one. Circa 1830s, this matron wears the typical mutton chop sleeves, lace bonnet and hairdo of her time, and, of a certain age, is content to pose as her hands work the 3 slender knitting needles she holds. Stockings, perhaps, or sleeves for a baby sweater. The artist captured her beautiful working hands as well as every other detail. The miniature is shown here under the old convex cover glass, so small glares from the lights, but there isn't a bit of damage to this painting. There is, also, no signature. I didn't open it to photograph her without the cover glass, which I often do. Someone did so back in 1977, cleaned the glass well and re-sealed it from the backside (note collector's name/date) and I'm loathe to open a sealed anything.
Very good to excellent condition, no flaws notable on that fabulous painting. It might be possible there would be a signature on the very edge of wafer, which is sometimes the case, or further information within the seal. I'll leave it to her next owner to decide if they want to search more deeply. The old frame shows an edge flaw to her right, about 3 o'clock position, and shows age. Measurements are noted on our photos.
