Streetartnews said: "At the break of dawn, the British street artist showed up with a maintenance van and covered all the sides with tarpaulin to execute his new stencil.
"This piece is showing three government secret agents quietly spying on various phone conversations. Quite a strong statement against the recent privacy issues we experienced this past year with the NSA and such.
"Banksy didn't pick Cheltenham randomly as the city is home of the GCHQ (Government Communications Headquarters).
"While not officially confirmed by his website, this piece has has all the Banksy characteristics in narrative, style and execution."
A GCHQ spokesperson told the BBC: "This is the first time we have ever been asked to comment on art.
"Although we are not qualified critics, we are as intrigued as the rest of the residents of Cheltenham about the appearance of the mysterious artwork.
"For those who are interested, our website gives a glimpse of what modern-day intelligence operatives are really like, although some may be disappointed by the lack of trench coats and dark glasses."
