It is a White House photo twenty-seven years in the making.
President Bush stood side-by-side with President-Elect Barack Obama and former Presidents Bush, Carter and Clinton during a photo-op in the Oval Office.
It is the first time all living former presidents were at the White House at the same time since October 1981.
President Bush wished Obama the best of luck -- President Bush invited the former and future Commanders-in-Chief for lunch.
Bush and Obama also met in private for about thirty minutes.
