Jon Hamm & John Slattery on Mad Men Set Pictures

Jon Hamm wasn't the only small screen star wearing a suit for the Mad Men cameras in LA yesterday. He was joined by John Slattery, Vincent Kartheiser, and Rich Sommer for filming after the costars returned from their Thanksgiving break. The guys celebrated the beginning of the holiday season, but the cast already had a big highlight back in September when the series was honored with the Emmy for best drama. The leading men partied together post-win, though they were missing their leading lady, January Jones, who had just given birth to baby Xander. She's since been spotted on set and even brought her young son along to meet the cast. Season five doesn't return to AMC until next year, but if you have a fanatic in your life, there are lots of Mad Men gift ideas that would be great to help ease the wait.
