caption: The image shows a book with a cover page featuring a woman in a dress and stockings, with the words "Betty Rumba" written across the top. The woman has a confident and determined expression on her face, and her hair is styled in a classic 1950s look. She is wearing a white dress with a high neckline and long sleeves, and she is standing in a relaxed pose with her hands clasped in front of her. The background of the cover page is a light blue color, and the text is written in a bold, black font.
