Barack Obama's holiday card featured the family dog, Bo.
While it may be less common these days to send a holiday greeting via snail mail, the White House has yet to let go of its nearly 90-year tradition.
Starting with Calvin Coolidge in 1927, the long-standing practice requires each sitting US President to let their staff and supporters know they wish them a happy holidays.
Who gets the cards changes from year to year, and each card is unique.
With the help of the White House Historical Association, we've pulled together65 White House holiday cards from the past eight decades years. Happy holidays!
