L’Enseigne de Gersaint (Charlottenburg Palace, Berlin) was painted at the end of 1720 and was one of Watteau's final paintings. It depicts the art dealer Edme-François Gersaint at work on the Pont Notre-Dame in Paris. Watteau made the painting as a sign for his friend Gersaint's shop.
This drawing was a preparatory piece for a scene depicted on the left-hand side of the painting. It shows one man taking a portrait of Louis XIV from a box, while another carries a mirror. The juxtaposition of the fine hatching and thick lines helps to bring this dynamic composition to life. Watteau's use of the so-called trois crayons technique (i.e. the combination of black, red and white chalk) also adds to this sense of spontaneity.
