Prompt
Generate a realistic portrait of Sir Arthur Keith, a middle-aged British man with a dignified expression, wearing formal attire, including a suit and tie, sitting in a study with books and papers surrounding him, with a subtle background hinting at his connection to anatomy and anthropology, such as a skull or a fossil. The style should be reminiscent of a classic, early 20th-century British portrait, with attention to detail and a sense of gravitas.
