Britain's Royal Mail is marking the 50th anniversary of the popular show with a series of stamps featuring each of the 11 actors who have played the title role, known as the Doctor. Those featured include the most recent actor, Matt Smith, as well as past Time Lords such as David Tennant and Christopher Eccleston.
The series will also include a miniature sheet that brings together Second Class stamps featuring the Doctor's time-traveling machine and four of his iconic foes - a Dalek, an Ood, a Weeping Angel and a Cyberman.
The stamps honoring the cult British television program will be available starting at the end of March.
