English: The Prince Imperial, son of Napoleon III, sits strapped securely into a seat on his horse's back, a model subject for the camera. An attendant at the left steadies the horse so that the little prince remains picture-perfect in the center of the backdrop erected for the photograph. The horse stands upon a rug that serves as a formalizing element, making the scene appear more regal. The Emperor Napoleon III himself stands off to the right in perfect profile, supervising the scene with his dog and forming a framing mirror-image of the horse and attendant on the other side.
Pierre-Louis Pierson placed his camera far enough back from the Prince to capture the entire scene and all the players, but this was not the version sold as a popular carte-de-visite. The carte-de-visite image was cropped so that only the Prince upon his horse was visible.
