Real Picture of the Tardis from 1939.

In 1939, Dr. Who arrives in London to save the world.  The BBC, unwitting of the significance of the public call box, use it to film a public service advertisement on vehicle safety and what to do if you are in a driving accident.  Meanwhile, the Doctor and his Companion wait inside impatiently, hoping alien forces do not win before the film crew leaves them alone.

At least, that is the way I see it…
