La fille mal gardé, or, Jack in the box [graphic]

"A pretty young woman stands with a warning finger to her lips, while an ugly old man leaves the room (left) holding heavy keys and a padlock. A young military officer, concealed in a brass-bound treasure-chest, raises the lid to look amorously at the woman. The head of an African servant looks up from stairs leading to the door. The window (right) is heavily barred; on it are hung a watchman's rattle and a blunderbuss."--British Museum online catalogue
