Two dioramas, one from the Musée des Cultures Guyanaises, Cayenne, and the other from the Musée des Beaux-Arts, Dunkirk, were entrusted to the C2RMF for analysis and restoration. A comparative study provided greater insight into how they were made and technical data about their manufacture that was useful for restoring the diorama in the Musée des Beaux-Arts, Dunkirk. The future restoration of the diorama from the Musée des Cultures Guyanaises will complement the data already collected and, through comparison with the difficulties involved in the restoration of Dunkirk’s diorama, will help us to better understand the notable differences in alteration, particularly, in the faces. These dissimilarities are all the more disconcerting since these illustrations of everyday life in Suriname are characterised more by stylistic, technical and iconographic similarities than by their differences.
