Ad of the Week: Tate Britain, Welcome To London

Posters are getting interesting. We’ve recently seen brilliant responsive digital posters for BA and Swedish haircare firm Apotek Hjärtat, and now Tate Britain has launched an ad campaign which features different combinations of images and text depending on the time of day, the weather and even the presence of a full moon. The work, created by Liveposter, is our Ad of the Week.
