Holsten UK is underpinning its latest ad campaign with the UK's biggest permanent poster, occupying a 900sqm site in Manchester's Eastlands adjacent to the City of Manchester Stadium and Asda's biggest UK superstore. The giant poster will feature the 'Holsten Perfect Husband' - a heavily pierced man reading a book on how to be the perfect partner - with the strapline 'It's what's inside that counts'. The poster campaign, created by TBWA\London and planned and bought by Starcom MediaVest, will stay on the site for two months. The site, managed by The Big Poster Company, covers a gasometer. The Big Poster Company has signed up with National Grid Transco to develop sites on 25 gasometers in prime UK locations.
