A ninth-plate daguerreotype portrait of a painting of an unidentified young woman, housed in its original thermoplastic union case and likely produced in the early-to-mid 1840s based on the hairstyle and dress conventions visible in the image. The format and intimate scale place this among the earliest American portrait daguerreotypes, made during the medium's first decade of widespread practice. No photographer's imprint is visible on the case or mount.

The subject wears a dark off-the-shoulder dress with a narrow white collar at the neckline and directs a steady, composed gaze toward the camera. Her dark hair is center-parted and drawn smoothly back, with long clustered sausage curls falling at each temple, a fashionable style of the early 1840s. A small pendant or brooch is faintly visible at her throat, and her three-quarter pose adds depth to the compact oval composition.

The sausage curl hairstyle was at its peak popularity in American and European fashion between roughly 1838 and 1848, offering a useful bracket for dating the image. The oval brass mat is set within a gilt floral-patterned preserver, and the case interior is lined with embossed red velvet on the opposing leaf. The thermoplastic exterior features a geometric medallion pattern with interlocking circles and diagonal bands.
