From December 1972 to May 1973, the Science Museum
- in South Kensington, London -
BBC TV Special Effects Exhibition.
Part of this exhibition featured Doctor Who.
(Apparently, Jon Pertwee, Nicholas Courtney, and Katy Manning
had made an appearance for the launch in December)
There was a walk-through mock-up of the TARDIS console room,
a couple of Daleks, a Sea Devil, and some other Doctor Who 'monsters',
and a display comprising a few models of spacecraft from episodes of the programme.
