18th Century Italian Neoclassical Oil on Canvas Screen with Trompe L’œil

These large screen is composed of four panels in oil on canvas painted. Neoclassical, dating to the second half of the 18th century.
Each panel represents a trompe l’oeil, with a classical architecture with square section marble columns and large clogging. Inside the pink space of the first and third panels are painted, as inserted in a niche with bronze frame, ancient busts in marble: it is, as it reads from the cartouches in faux marble below, of the busts of Emperor Marcus Aurelius
