The vividly painted floral arrangement is mounted on an en grisaille neo classical stand. The whole painting, including its matching chatelaine, lies on a grey ground shaded left to right and should be compared to one by William Allam, in Jagger’s, The Artistry of the English Watch. Although no clues exist regarding the identity of the enameller, some speculation has been raised that it could be Moser’s daughter, Mary, who had exhibited similar paintings, though no hard evidence has come to light which would substantiate this possibility. John Scott was working at Gloucester Street before 1784.
