Picture taken on October 12, 2012 in Vallon-Pont-d'Arc of a prototype of painting of the facsimile of the Chauvet cave, which contains some of the earliest known cave paintings Arc, on the day of its launching. The access to Chauvet's cave is severely restricted owing to the experience with decorated caves such as Lascaux, where the admission of visitors on a large scale led to the growth of mold on the walls that damaged the art in places.
