Y’know, we’d always assumed that the “Welcome To Central City” signs in The Flash were simply CGed onto existing billboards, but not according to these rather marvellous two pics from HollywoodNorth.buzz. They show crew members on the team making a not-so-subtle alteration to the sign at the show’s Vancouver location – “Home of… Kid Flash”. The main question has to be, is this Central on our Earth or one of the numerous parallel Earths? We’re guessing it is Earth Prime and the pretty soon our Central City is going to learn it has a new Speedster hero. Which makes a change from a new Speedster supervillain.
