there is no record of Oprah Winfrey selling a Gustav Klimt painting for $150 million. It's possible that such a transaction occurred , or it could be a rumor or misinformation.
To get the most accurate and up-to-date information on this matter, I recommend checking recent news sources or conducting an online search for the latest updates on Oprah Winfrey's art collection and any potential sales. Celebrity financial information, especially related to private transactions, is often not readily available or kept confidential.
