A new Banksy-style street art mural that appeared in Cheltenham, England, on Sunday. Photo by Kathryn Wright It's a known fact that the city of Cheltenham is home to the Government Communications Headquarters (GCHQ), the UK's counterpart to the National Security Agency. And on Sunday, locals received a GCHQ-themed surprise—new street art around a public telephone booth that depicts men in trench coats secretly recording what happens inside. The mural was painted at the intersection of Fairview Road and Hewlett Road, just three miles from GCHQ's main building. Local residents believe that the mural could be the work of the British graffiti artist Banksy, according to The Telegraph. Banksy is famous for his various street art "vandalism" projects across the globe, which often comment on social and political themes. While the wiretapping techniques in the mural appear historically bent, the theme of government eavesdropping on phone calls is quite timely.
