Prompt
Generate a realistic image of an elderly American man in his 80s or 90s, sitting in a library or office surrounded by books and papers, with a warm and gentle expression. He has a slight smile on his face and is wearing glasses perched on the end of his nose. He is dressed in a button-down shirt and a pair of khaki pants, giving off a sense of intellectualism and professionalism. In the background, there are hints of Florida landscape, such as palm trees or a map of the state, to reflect his connection to the region. The overall style should be a dignified and respectful representation of a historian and author, capturing the essence of Michael Gannon.
