there was no record of Oprah Winfrey selling a Gustav Klimt painting for $150 million. It's possible that this event may have occurred , or there might be some confusion with other art transactions involving different individuals.
For the most accurate and up-to-date information about Oprah Winfrey's art collection and any recent sales, I recommend checking reliable news sources or financial reports. Keep in mind that art sales can involve private transactions, and specific details may not always be readily available to the public.
