This year's ornament honors President Calvin Coolidge. It's design of a Christmas tree includes ornaments on that tree representing an event in Coolidge's life. These include the general store/home that Coolidge was born in, Coolidge's love of baseball, a boyhood ritual in which Coolidge and friends stole a cannon from a neighboring town (who would steal it back, and the cycle continued), eagle feathers representing the Indian Citizenship Act, the Distinguished Flying Cross which Coolidge awarded to Charles Lindbergh, the cowboy hat Coolidge was given during his vacation to the Black Hills of South Dakota, his fishing tackle box, the kerosene lamp that lit his swearing in as president by his father, the White House after renovations done during Coolidge's time in office, a radio microphone commemorating his being the first president to address the nation by radio, a campaign button from the 1924 election, Grace Coolidge's pet raccoon Rebecca, the dedication of Mount Rushmore, and a pair of socks. The socks represent an anecdote in which, shortly after their marriage in 1905, Coolidge presented his new wife Grace with a basket of pairs of socks to mend. When she asked him if he had married her to get his socks darned, he replied, “No, but I find it mighty handy.”
The White House Historical Association is a charitable nonprofit institution dedicated to preserving the historic legacy of the White House.
