@WendyyWolfe It’s from a 1967 tv show called ‘The Prisoner’, which is about a secret agent who is trying to escape ‘The Village’. The inhabitants of the Village are only known by their numbers and wear badges with their numbers on them. The badge has the emblem of the Village, which is a stylised image of an old penny-farthing bicycle. The main character (the Prisoner, played by Patrick McGoohan) is only ever known as Number 6.
The series has episodes about mind control, identity, propaganda, social control … all sorts of things that are still relevant. You can find the show on YouTube if you search for it.
