Prompt
Create a realistic portrait image of Charles Sumner, a prominent American politician and a leading figure in the Radical Republican movement, sitting in a dignified pose with a backdrop that reflects his influential life, such as the United States Senate or a 19th-century Boston street; incorporate subtle hints at his notable achievements and struggles, like a faint image of the Civil Rights Act of 1875 or a discreet reference to the caning by Preston Brooks, in a style that echoes 19th-century American realism, with a focus on conveying Sumner's resilience, intellectual depth, and commitment to abolitionism and racial equality.
