‘Walk’ By Vaughan Oliver

This month Do The Green Thing in collaboration with WWF UK and Pentagram have launched 29 Posters for a Planet, a collection of inspiring posters made by world class creatives in support of Earth Hour. Earth Hour is the world’s largest mass participation event, where people switch their lights off between 8:30-9:30pm on March 29th to show their commitment to the planet.

This year’s contributor list is impressive. Supporters include Roald Dahl childrens’ book illustrator Sir Quentin Blake, Obama’s 2012 Design Director Josh Higgins, fashion designer Paul Smith, Google Labs Creative Director Tom Uglow and many more.
