So-called portrait of louis françois, prince of conti (1717-1776), but is probably a depiction of gustav iii of sweden (1746-1792) identification proposed by user ecummenic (talk) based on the comparison with a portrait of gustav iii with his brothers of 1771 by alexander roslin (see image below) and the lack of physical resemblance with the prince of conti. Object Type: manuscript illumination. Date: 18th century. Dimensions: height: 2.6 cm (1 in); width: 2.3 cm (0.9 in). Medium: miniature portrait. Collection: Condé Museum.
