Prompt
Generate an image of a 19th-century British clerk, specifically John Dickens, in a formal attire, sitting at a desk with papers and a quill, with a stern expression, in a realistic style, hinting at his occupation and notoriety, with a background that subtly suggests his connection to the Navy Pay Office and a faint, discreet indication of his time at Marshalsea Debtors' Prison, paying homage to his role as the father of Charles Dickens.
