Now, those images come to life in a new teaser trailer for the return of Season 7, which will bring about the end of an era this spring. It seems Don is throwing a lavish lawn party, and everyone has been invited.

Don't look too hard for any clues in this first footage, though. While the sneak peek clearly indicates Don Draper (Jon Hamm) and associates are moving out of the 60s and into the 70s, there is not much to be learned in this glamorous photo-shoot stye teaser featuring the main cast as they show off some of their new fashions. About these final episodes, series creator Matthew Weiner stated earlier this year:

"What an incredible journey this has been. I take great pride in what the entire Mad Men team was able to create episode after episode, season after season. We sincerely thank the fans for joining us on this ride and hope it has meant as much to them as it has to us."

Mad Men returns to AMC Sunday, April 5 at 10:00 p.m. ET/PT. But before we say good-bye to the complex lives of Don, Peggy, Roger, Joan, Betty and Pete, and their families, colleagues, rivals and love interests, this spring, take a look as they enjoy one last outing together:
