I keep seeing a small Tardis with a '50' on the front doors (currently can be seen top right hand side on any Gallifrey Base page). Didn't know if that was a fan mock up or had been released by the BBC.
BBC America has the same logo at the top of the screen during the Doctors Revisited and The Aztecs. So, I guess it's official.
There's that. There's also a version of the Pertwee/McGann logo that has a fade out at the bottom (to make it look like the Hartnell logo) for the 50th.
^ Poor Eight is still stuck with that one standard stock image from the movie that's been used ad nauseum.
Yes, it's franchise-wide. You'll see it on most, if not all, merchandise this year, such as BBC Books' reprints of classic novels, one from each Doctor.
