What a difference four years makes! He’s quite a bit grayer and his smile, much wider.

President Obama’s official portrait for his second term, posted Friday to the White House Flickr page, holds a different tone than the photo taken four years ago right after he won his first presidential election.

Obama posed for the new portrait in the Oval Office, with the American and presidential flags on either side of him. This time around, more of Obama’s torso is shown, as his arms are folded across his body, but he holds a wide grin missing from his last head-and-shoulder photo.

White House photographer, Pete Souza, took the portrait on Dec. 6, 2012.
Obama's new portrait made us want to remember how other presidents transformed during their time in the White House, so we took a look back at how the last three Commanders-in-chief aged in office:

George H.W. Bush was inaugurated in 1989, and had picked up a snazzy pair of shades by the time he left office in January of 1993.

When Bill Clinton was inaugurated at age 46, he was the nation's third-youngest president:

Bill Clinton left office with a full head of gray hair eight years after he began.

Here's George W. Bush in January of 2001 and again in January of 2009:
