This background attempts to capture the essence of London in a single frame. A telephone box sits against the flag of the United Kingdom; nearby, the words "London" and "calling" appear on splattered red-and-blue paint. The random look of the paint adds a punk appeal.
There's also a definite pop art influence in the flag and in the traditional look of the telephone booth, but the graphic stays patriotic by sticking to the flag's basic color scheme. It creates an exciting mood, and it's excellent for building a sense of pride in the city of London or in the United Kingdom as a whole.
