Each year Assistance League of Northern Virginia brightens the Christmas tree by offering a uniquely designed White House Christmas ornament. Each year, the White House Historical Association creates a new design to commemorate a special event, person, or place.
From their website:
The Official 2023 White House Christmas Ornament, the only ornament of its kind, is produced by the White House Historical Association, a private, nonpartisan organization, and made in America by a veteran-founded business. Each ornament funds the work of our historians, researchers, and educators to open the doors to the rich history of the “people’s house” for millions of Americans.
And the cherry on top: each ornament has a unique serial number with which you can register your very own piece of history!
