Before we finally see the new look, but still the same old, Tardis in this Sunday's episode of Doctor Who - Series 11 entitled 'The Ghost Monument', I've just noticed something new about the new look Police Box prop that has not been noticable on anything else I've seen before.
I've just noticed this clip relating to the BBC's Children in Need on the Twitter page of YouTuber's 'The Who Addicts', and I've come notice on a short little Video that if you look very carefully at the 'Pull To Open' sign, not only does it appear to be black with white text, but it's also slightly transparent, as you can see inside it slightly.
To see the Video, click the following link and scroll down to the post that says This is just wonderful
By the way, episode 3 of series 11 has been revealed to be called 'Rosa' . . that's gonna confuse fan's in future surely with series 1's 'Rose' !!
