The standing boy with a hurdy-gurdy at his back is Marie-Gabriel-Florent-Auguste, Comte de Choiseul-Beaupré (1752–1817). Beside him, pointing to a peep-show box, sits his younger brother, Michel-Félix-Victor, Chevalier de Choiseul-Daillecourt (1754–1815). The boys were cousins of the celebrated Duc de Choiseul, foreign minister under Louis XV. In costuming his subjects as Savoyards, the itinerants from Savoy who wandered over France working at odd jobs and in street fairs to support the families they left at home, Drouais probably intended to depict the brothers as models of filial devotion — a conceit reinforced by the presence of the faithful dog. It may be noted that the boys’ disheveled garments are made of sumptuous velvet and that their buttons are of gold.
