The mural of graffiti appeared in April 2014 on the outer wall of a house on two floors of the nineteenth century in the town of Cheltenham.
The painting, made around a real phone booth, shows three spies with aesthetics and media 1950, dressed in trench coats, sunglasses and hat, pointing their microphones and recorders into the cabin itself.
In February 2015, due to the great expectations that emerged after the appearance of the mural, the municipal council of the town adopted a regulation under which the work was protected and prohibited moving it from its location without the approval of the authorities.
Despite this protection, the work had been vandalized with graffiti and graffiti on numerous occasions.
"The protection of Banksy's work had always been one of our priorities, and the owner knew it was an obligation to protect it while they carry out the works," he said.
