vagueYesterday, I succumbed to a Vogue email inviting subscribers to download its latest iPad app and access exclusive digital-only content. How now. But one of the first articles that popped up in the app, Kate Moss Isn’t the First Model to Run Her Own Agency,” inexplicably neglects several models who were no less than pioneers of the posing trade. Fortunately, you can read all about Dorian Leigh, Natalie Nickerson and Simone d’Aillencourt, among other model entrepreneurs, in the New York Times bestseller Model, and learn what fashion magazines like Vogue won’t tell you about fashion photography in the new Focus.
