Gale is a patroness of art, and the only one who receives Bill, a vendor of pictures. She declares that he must paint her as "December Afternoon." She gets ready to pose, with her feet in a basin of water for realism, and Bill has to make good his bluff of being an artist. He enlists the aid of Lillian, the maid. She snaps the model, and goes out to have the plate developed and enlarged. As revenge upon her mistress, who has found fault with her, Lillian changes the enlarged portrait for that of a donkey. A reception is held for the ceremony of unveiling the picture, and consternation reigns when the substitution is discovered. Bill is kicked out, and Gale gives up the patronage of art.
