Prompt
Generate a realistic portrait of Josiah Quincy, an 18th-century American politician, in a colonial-style setting. He should be depicted wearing formal attire, such as a powdered wig, coat, and waistcoat, with a serious expression. In the background, include subtle hints of his involvement in the American Revolution, such as a faint image of the Massachusetts Provincial Congress or a liberty bell. The style should be reminiscent of classic American colonial-era portraiture.
