An unsigned variant of the present miniature by Sicardi is in the Louvre (see P. Jean-Richard, Miniatures sur ivoire. Musée du Louvre. Musée d'Orsay, Paris, 1994, no. 586).
Marie-Jacobée Balguerie, a daughter of Jean Balguerie and Marguerite Tarteyron, was married to André Prunet (d. 1799).
The sitter belonged to a well-known family of ship-owners from Bordeaux. This substantiates the theory put forward by Jacqueline Du Pasquier that the elusive artist D.M. worked in Bordeaux (see exhibition catalogue l'âge d'or du petit portrait, Bordeaux, Geneva, Paris, 1995-1996, pp. 48-49, 140, no. 205).
