The Bat Signal For Real

In the movies and the TV show, the Bat Signal was a sure sign that something bad was occurring in Gotham City and the services of the Dark Knight are required, so what is this bat signal doing in the US city of Pittsburgh?

Well it would seem that this cool illumination has been set up by the city authorities, not for help but in appreciation of the film The Dark Knight Rises, using the city as a backdrop!
