Very few examples of Wilton’s work are known. However, two which can be positively identified have been dated to 1809 and the 1820s. This long time scale, taken with the existence of a printed trade label, implies that Wilton may have been more prolific than the number of existent silhouettes implies. Known silhouettes are painted in a simple style, with clothing crudely shown and little detail on the body. They tend to be very small, around two inches.
