Happy Holidays from the White House: See 91 years of presidents' Christmas cards, from Trump to JFK to Coolidge

• The first family sends staff and supporters a holiday card every year.
• The White House's annual tradition dates back to 1927.
• President Donald Trump's two cards are very similar, both wishing people a "Merry Christmas and a Happy New Year."

While it may be less common these days to send a holiday greeting via snail mail these days, the White House hasn't let go of its 91-year tradition.

Starting with Calvin Coolidge in 1927, each sitting US president has wished their staff and supporters a happy holiday. Each card is unique, and recipients change from year to year.

With the help of the White House Historical Association, we've pulled together 66 White House holiday cards from the past eight decades. Happy holidays!
