This plate, taken from Études paléoethnologiques dans le Bassin du Rhône and glued to a page of Album noir no. 2, shows some of the archaeological objects discovered at the site of Réallon, in the Hautes-Alpes region. The find, which included many objects in copper alloy, including penannular bracelets decorated with incised geometric patterns, was made in 1870 by Ernest Chantre, an archaeologist and highly active correspondent of the Commission de Topographie des Gaules. Some of the objects were given to the musée de Saint-Germain in 1870.
