In the cult BBC drama ‘Dr. Who’ the Dr travels in a time machine called the TARDIS (type 40) that uses a ‘chameleon circuit to change its outer visible form to fit with the local surroundings.
Unfortunately the chameleon circuit broke when the TARDIS was disguised as a 1950’s London blue Police box. They are essentially a mini police station for use by Police people, and members of the public can use them to (phone) call the police. Police boxes were first used in Albany NY (1877) soon after the telephone was invented! The first boxes in Britain were placed in Glasgow (1891).
By the time I was old enough to visit London (1970s) the London police boxes had long since been removed.
This green police box is alive today, in Sheffield!
Seeing this Box kept me happy for weeks, I hope the photograph does something pleasing for you too …
