"This hitherto unrecorded portrait of Georgiana relates to several works at Chatsworth by John Downman, which are studies for the double portrait of her and Lady Elizabeth Foster which now hangs at Ickworth house. Another virtually identical study to the portrait presented here is in the Fitzwilliam Museum, Cambridge (no. 2314.15). Typical of Downman's technique and style of the 1780s this sketch has a spontaneity and freshness of approach that highlights both the beauty and realism of the sitter without resorting to unnecessary flattery."

"Downman completed this rare sketch whilst at the height of his popularity in London. Within a few years of his return to the capital in 1779 he had attained a reputation as one of the most fashionable portraitists of the day and by 1786 he was reported in the press as "universally admired & sought after by the first people of rank and taste" (Morning Post, May 4th 1786). One of the keys to his success was his recognition of representing his sitters in the fashions of the day, leading to commissions not only from high society and royalty but also from the professional classes."

"With thanks to Charles Noble, the Curator at Chatsworth House, who confirmed the attribution and identity of the sitter."
