there was no information indicating that Oprah Winfrey owned a Gustav Klimt painting, let alone selling it for $150 million. It is essential to note that my information might be outdated, and I recommend checking more recent sources for the latest news on Oprah Winfrey's art collection or any potential sales.
Please keep in mind that art prices and sales can fluctuate significantly, and the value of a painting can vary depending on factors such as the specific artwork, its condition, the current art market trends, and the buyer's willingness to pay.
