Painted plaster is a technique used to produce copies. These copies are not intended for exhibition, but rather for large-scale production using resistant, durable materials such as bronze and marble. These materials were also used to create other models of Le Prince Impérial and his Chien Néro. This work in painted plaster is therefore based on the marble original housed in the Musée d'Orsay. The painted coating over the plaster serves to protect the material, preventing damage to the statue in question. The model was also reproduced in bronze in various sizes.
