Prompt
Create an image of Piero Sraffa, a middle-aged Italian man with a serious expression, sitting in a classic armchair in a library or study, surrounded by books and papers. He is wearing a suit and tie, and has a thoughtful gaze. In the background, there is a bookshelf with some notable works visible, such as "Production of Commodities by Means of Commodities". The style should be realistic, with muted colors and a sense of intellectualism. The image should convey a sense of authority and expertise in economics.
