The final seven episodes of Mad Men begin airing in just six weeks, which means the AMC buzz machine surrounding the show has kicked into gear. Last week brought the first teaser pictures and video trailer for season seven’s conclusion, along with the news that Don Draper’s hat and suit are headed to the Smithsonian. And today, before it begins popping up on billboards and in magazine ads, Vulture has the exclusive unveiling of the last official poster for Mad Men — the emblematic image that will forever stand as the graphical representation of season seven’s second half. Series creator Matthew Weiner and AMC marketing chief Linda Schupack agreed to talk to us about the poster. Since the season hasn’t started and Weiner notoriously guards against spoilers, they didn’t reveal anything concrete about what’s to come on the show. But they did discuss five elements of the image and offer hints — teeny, tiny hints — as to what they might mean.
