caption: The image shows a poster featuring a drawing of a woman with long hair and a man in a suit, with the title of the book, "Er Libris" by Arthur Dews, written in bold lettering above her. The woman is wearing a long, flowing dress and has a serious expression on her face, while the man is looking off to the side with a thoughtful expression. The background of the poster is a deep blue, with a few stars twinkling in the night sky.
