Daleks on "Vision On" (RIP Tony Hart) 

A brilliant minute-long clip from Vision On, shown first on 1st December 1972. Tony Hart draws the outline of a Dalek using a football-pitch line-marking machine, and then it 'comes to life'. Dalek spods will recognise these as the 1972 BBC Visual Effects wooden Dalek builds, appearing in their gunmetal 'Planet Of The Daleks' livery (though I think there's a couple of Aaru skirt sections in there as well)
