there is no record of Oprah Winfrey selling a Gustav Klimt painting for $150 million. It is possible that this event may have occurred , or it could be a misunderstanding or misinformation.
To get the most accurate and up-to-date information, I recommend checking the latest news sources or conducting a search specifically for Oprah Winfrey's art sales and transactions. Keep in mind that financial details of private art transactions may not always be publicly disclosed, so the exact amount she might have made from any potential sale may not be readily available.
