Prompt
"Generate a realistic portrait of Alan Greenspan, a middle-aged man with a distinguished appearance, sitting in a formal setting with a subtle background that hints at his connection to finance and economics, such as a bookshelf with titles related to economics or a subtle image of the US Capitol or Federal Reserve in the background. He should be dressed in formal attire, possibly a suit and tie, with a calm and introspective expression, conveying his role as a renowned economist and former Chairman of the Federal Reserve. Incorporate elements that reflect his personality and achievements, such as a pen in his hand or a book nearby, symbolizing his work as an author and economist."
