Prompt
Generate an image of a portrait of Sir Henry Campbell-Bannerman, a human, dressed in formal Victorian-era attire, sitting in a dignified pose, with a background that reflects his British and political heritage, possibly with a hint of Scottish influence, given his birthplace in Glasgow, Scotland; he should be depicted as an older man, given his dates of birth and death (1836-1908), with a thoughtful expression, conveying his role as a significant political figure, specifically the Prime Minister of the United Kingdom.
