The Ten Doctors

Do you recognize this person?

If you answered, "No. And what do you mean, 'This person?' There's ten people there," then you may as well stop reading right now.

But if you answered, "Yes! But he got the colors wrong on Tom Baker's scarf," then you really need to be reading The Ten Doctors.

(Yes, I'd previously mentioned this in a 7 Links post, but I wanted to give it the prominence it deserves.)
