Prompt
Create a realistic portrait of Gertrude Elles, a British geologist and academic, in a formal setting, possibly in a university office or a paleontology laboratory, surrounded by books, papers, and fossils, particularly graptolites, that she is known for studying; she should be dressed in attire typical of a British academic in the early 20th century, with a thoughtful expression, and perhaps holding a magnifying glass or a notebook, reflecting her contributions to paleontology and stratigraphy.
