Well, if you're throwing a visual treats party to celebrate your birthday, why not utilize the obvious talents of Kate Upton on the cover of your special edition. Everything about Kate Upton in a revealing outfit says 'special occasion', if not, 'men with little self-control ought to remain seated'.
Now, this Vanity Fair anniversary special edition looks likes an homage to Marilyn perhaps from her Playboy posing days, not really sure, I'd have to start reading the articles and you know reading hurts my head. Either way, it's Kate Upton cleavetastic, which on the scale of party favors, ranks right above chips and soda and right below exactly nothing. Enjoy.
