This painting is typical of the portraits produced by Danish artists of the 1820s and 30s, the size of the canvas, representation of the sitter and execution point to one of less than a handful of artists, so in 2012 we requested an opinion from the Chief Curator, Kasper Monrad, at The National Gallery of Denmark. Below is a copy of his written reply.
The painting style seems close to that of Christian Albrecht Jensen (1792-1870), who painted several portraits of the same type, often with a lively characterization of the sitter. If it is indeed by Jensen, it is not a sketch, but a finished painting. During his own lifetime, he was known-and scolded by the Danish critics! – For his sketchy painting style.
Jensen had several English customers, however, and could be one of the portraits he painted on his trips to England in 1837, 1838, 1839-40, 1843 and 1853.

Condition: The painting is in excellent condition having benefited from a light clean. The frame has had an old layer of gold paint removed to expose some of the original gilding. Any remaining areas have been re-gilded and aged. The original moulded decoration is intact. All work has been carried out by accredited conservators.
The young lady (seen in our B&W photograph) is wearing a similar necklace to the one in our portrait; the photograph is illustrated in the first volume by Sigurd Schultz: C. A. Jensen. I-II. Copenhagen, 1932. No.124, page 209. Dated 1827.
