The teaser for the final episodes of "Mad Men" has arrived

The first teaser for the second half of "Mad Men's" final season has finally arrived, and judging by the outfits and the song choice (Diana Ross' "Love Hangover”), Don and the gang appear to have been catapulted forward to the mid-'70s. As with any “Mad Men” teaser, it yields nothing in the way of plot, but plenty in the way of beauteous bell-bottoms, floral maxi dresses, high collars, men in tweed, garden parties, martini glasses and Don blowing wisps of cigarette smoke listlessly into the summer breeze.
