The dossier 2 space is normally used to display graphical pieces of art or models concerning the Garnier opera house, the building that best symbolises the Second Empire architecture. During the Toulouse-Lautrec exhibition in the Grand Palais, the work of the painter and theatre decorator Maxime Dethomas was displayed in the Musée d'Orsay.
This theatre decorator (Opéra, Théâtre des Arts, Comédie-Française) was also a much liked painter and engraver, a friend of Degas and above all of Toulouse-Lautrec who painted his portrait in 1896. He realised vigorous charcoal drawings showing views of Paris and Italy, as well as portraits of his friends Edmond Rostand, Catulle Mendès, Lautrec, Henri de Régnier whose Esquisse Vénitiennes he illustrated, Forain, etc. He also illustrated works by Maurice Donnay, Octave Mirbeau and, in 1922, Molière's theatre.
A large part of Maxime Dethomas's work is kept in the Musée de l'opéra.
