HAPPY HOLIDAYS FROM THE WHITE HOUSE: See the presidents' Christmas cards, from Coolidge to Obama

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 holiday.

Who gets to receive the cards changes from year to year, and each card is unique.

With the help of the White House Historical Association, we've pulled together 67 White House holiday cards from the past eight decades. Happy holidays!
