Up for your consideration is this stunning Victorian antique hand painted porcelain electric table lamp. The hand painted lamp depicts the Georgiana Cavendish, Duchess of Devonshire with her flare and style large feathered hat, beautiful white shawl and stunning yellow gold dress with lovely pinkish red roses accented with enamel and gilt gold. The top of the lamp has a gold floral scroll. The base is metal with beaded floral & leaf design. The lamp measures 34" tall and the base measures 6 1/2" in diameter. The lamp has no chips or cracks. The portrait colors are bright and clean. 
This may very well be a Limoges. I see initials of RC. Just a note: Georgiana was the 4 times Great Aunt to Diana Princess of Wales. (This is similar to the Thomas Gainborough Portraits.)
