Vincent is known from one silhouette of a Lady Banks, apparently produced in 1804. It shows Lady Banks in a high feathered headdress typical of the period. The silhouette is approximately six inches high, painted in black on card and heavily gilded, with the signature ‘Vincent’ under the bust-line.
