Prompt
Create a realistic portrait of John Dickinson, an 18th-century American lawyer, politician, and writer, also known as the "Penman of the Revolution". Depict him in formal attire, sitting at a desk with a quill pen in hand, surrounded by papers and books, reflecting his occupation as a writer and politician. Incorporate subtle hints of his Quaker background and his roles as a governor of Pennsylvania and Delaware. The style should be reminiscent of 18th-century European portraiture, with attention to detail and historical accuracy.
