Thomason worked mainly in Dublin where he was advertising ‘Most Striking Likenesses in Miniature Profile’ and in the north of England where he was boldly 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’.
