Prompt
Generate a realistic image of a middle-aged man in a formal suit sitting at a piano, with a serious expression, in a style reminiscent of early 20th-century portrait photography. The man, Paul Wittgenstein, should be depicted with his left hand on the piano keys and his right arm absent or subtly hinted at being missing, conveying his identity as the one-armed pianist. The background should be a warm, elegant study or music room with classical music scores and perhaps a hint of Austrian or American influence, reflecting his nationality and later life in the United States.
