According to Wikipedia, the "Pot pourri à vaisseau or pot pourri en navire ('pot-pourri holder as a vessel/ship') is the shape used for a number of pot-pourri vases in the form of masted ships, first produced between the late 1750s to the early 1760s by the Sèvres manufactory near Paris." Below, the reverse side of the vase.
Right, "acquired by George IV, the vase in the Royal Collection is the largest of the three models of this shape produced at Sèvres...and depicts a genre scene...inspired by David Teniers the Younger (1610–90). The ends of the vase are in the form of a bowsprit, projecting from the jaws of a marine head, and at the masthead is a fluttering white pennant, patterned with fleurs-de-lis...purchased in 1759 at Versailles from Madame de Pompadour (who is known to have owned at least three examples of this model (including those now in the Louvre and Royal Collection)."
Below, the back of the vase shown above. Because the vases were most often displayed in front of a mirror, the backs were painted as beautifully as the fronts.
