At the recent Labour Party conference, Ed Miliband made a pledge to freeze energy bills until 2017 if he wins the next election. As part of the promotional material for this speech and beyond, agency TBWA/London created a multi-platform campaign which included a film, poster and microsite to explain the policy to voters.
The Hamiltons were drafted in to produce a sculpture of an envelope frozen in ice to represent a literal frozen bill. They had to be extremely careful to protect the delicate paper from being degraded by the water and the cold. The photograph was taken by Laurence Haskell and the video (below) was voiced by actor, Jason Isaacs.
