Andy Warhol created many a pop art portrait in his day, with his iconic brightly colored pieces featuring stars like Marilyn Monroe, Elizabeth Taylor and Elvis. And although his painting of Queen Elizabeth II might be the most well-known in terms of Warhol's royal pieces, he also immortalized a young Princess Diana and Prince Charles (now King Charles III) back in 1982.
Now both of these paintings, titled "Portrait of Princess Diana" and "Portrait of Prince Charles," are hitting the auction block in London on Thursday, Oct. 10—and they could bring in some serious cash.
