It's that time of year again, and the new White House Historical Association Christmas ornament is ready. This year, it's a beaut. Harking back to the 1889-1893, one-term administration of Benjamin Harrison, the colorful ornament is of a large Christmas tree decorated with roping, candles, and presents. And that's appropriate because Harrison was the first president to display a Christmas tree in the White House. He even gave out staff gifts. Married men received turkeys and single men fine gloves. The assumption was that families ate Christmas dinner at home, while singles had to dress up to go out.
