"Allons-y" to the tree! Doctor Who fans of all ages will love this Christmas tree ornament that depicts the tenth Doctor from the long-running BBC sci-fi series. Portrayed by David Tennant, this beloved incarnation of the Time Lord adventured through the universe from December 2005 – January 2010 with a variety of companions. The Doctor holds his sonic screwdriver aloft as a flashlight and wears his signature blue suit, a brown duster and red sneakers.
