Ford's new Mondeo is the star of what is believed to be the world's largest advertising poster in central England.

The gigantic poster carrying the slogan 'Built to Lead', measures 132 metres long and 23.7 metres high and covers a surface area equivalent to one and a half acres. Printed on PVC and mounted on scaffolding, the poster spans one side of the historic Fort Dunlop building adjacent to the M6 motorway in the Midlands city of Birmingham, Britain's second-largest metropolis.

The building, which is seen by thousands of motorists every day, was formally the headquarters of the Dunlop rubber company and is now undergoing extensive redevelopment. The Ford banner will be constructed over the next three weeks and will remain in place for six months.

Harry Torrance, commercial director of industry specialists Mega Profile, who are installing the giant poster, said: "We know it is the largest advertising poster in Europe and possibly the world, but we are waiting for confirmation of that from the Guinness Book of Records."
