Prompt
Create a realistic portrait of Friedrich von Wieser, an Austrian economist and member of the Austrian School of Economics, sitting in a formal attire, possibly with a suit and tie, in a study or library setting with books and papers around him, reflecting his contributions to economics, particularly his work on opportunity cost and imputation theory, with a thoughtful expression, in a style reminiscent of late 19th or early 20th-century European portraiture.
