caption: The image shows a drawing of a man and woman sitting on a pile of books in front of a bookshelf filled with books. The man is wearing a long coat and a hat, while the woman is wearing an apron and a dress. Both of them have a look of concentration on their faces, as if they are deep in thought. The bookshelves behind them are filled with a variety of books of different sizes and colors, and the paper they are sitting on has text written on it.
