Visitor name badges at Britain’s Cold War Revealed a temporary exhibition at The National Archives.

At the entrance to the bunker, visitors had to select a sticker indicating what kind of official they were, with options including Principle Medical Officer, Camp Commandant, Regional Scientific Advisor and so on. Later in the exhibition, visitors could fill out a travel pass, sit in a recreation of an MI5 office to look through facsimiles of secret documents, and use a typewriter to leave feedback about the exhibition.
