A 60ft poster of Calvin Klein's newest underwear male model has caused traffic congestion so much so that London's road safety officials have asked for the poster to be taken down.

Drivers have reportedly been slowing down to look at Travis Fimmel's billboard located at the junction of Tottenham Court Road and Oxford Street in London.

The Australian model became the first model since Kate Moss to be given an exclusive six-figure contract with Calvin Klein.

Calvin Klein is believed to be the first famous designer to boldly use male flesh to target the gay market since the early 1980s. The first Calvin Klein men's underwear campaign featured Tom Hinthaus in magazines and as a billboard in New York's Times Square.

Past models for Calvin Klein underwear include one-hit rapper Marky Mark, Antonio Sabato Jr. and Joel West.
