Season six of Mad Men will be kicking off on April 7th and, while few details are known, AMC has just released a set of beautiful, candid-seeming black and white promo shots to get us excited (as if we weren't already). Can any hints be gleaned from the photographs? Well, it looks like we're staying in the '60s, Pete has some very bold sideburns and Sally continues to march into womanhood. Other than that, it's all speculation though Don looks none too happy with Megan. Remember Don, you only live twice.
