Recorded by Jackson (The History of Silhouettes), who states that Walker painted silhouettes in the eighteenth century, and is known to have worked at Trowbridge, Wiltshire. The profilist may have been the miniaturist named Walker (fl. 1770), recorded (without initials) by Foskett, who may in turn have been the painter James Walker, recorded by Graves (The Society of Artists of Great Britain). Graves lists the following exhibits (Nos. 304-307) sent in to the Society of Artists, 1783, from 49 Upper Marylebone Street, near Titchfield Street, London: Head of Faith; The Village Doctress; Hobnelia, or the spell, Gay's Shepherd's Week; Portrait of a Lady.
All that is known of Walker's style as a profilist is that he worked on card, painting in black with white relief.
