Wigs on the Green has dated this piece to the 18th Century.
The silhouette is painted on plaster and sits in the original hammered brass frame.Both frame and silhouette are in fine condition though it lacks the artist’s trade label.

J. Thomason is known to have worked mainly in Dublin where he was advertising “Most Striking Likenesses in Miniature Profile” in 1792 and in the north of England where he was advertising in 1796 for “all persons who never could procure a good likeness before, to one more trial” when the artist promised “the fullest satisfaction, or will take nothing for his trouble”. That said, he would surely have been well-rewarded on this occasion!
