I want to know the answer to the following question:
Which magazine did Beyoncé pose for the cover, making her the first black female artist to do so?
All the background I'm provided with is that "In August, the cover of the September issue of Vogue magazine was unveiled online, Beyoncé as the cover star, becoming the first African-American artist and third African-American woman in general to cover the September issue.". Is that enough to answer the question?
