Here we go. This is what I was looking for:

Even if the doors and sign are a little wider than usual (and I can understand the reasons for this), it’s still exactly the size it should be.
The picture, now — that’s a different story. I’d like it a bit larger…
EDIT: My mother asks: “Did they grow smaller policemen in the 1970s?”
I recall reading somewhere that the reason for the new prop in 1976 was because the old one collapsed around Elizabeth Sladen. I think it was during production of The Masque of Mandragora.
The new prop is built to collapse. Maybe they’ve been preparing for Sladen’s return all along!
I like the title, though.
Bwahaha.
Did anyone else notice the similarity between the Metropolitan Police logo in that image and the second Doctor Who logo?
That’s… not a bad observation!
