Greenpeace: iamazonia

It's only when something is gone, that we realize how much we miss it. With this in mind, Greenpeace brought back one of Europe's most photographed tourist attractions - the giant 'I amsterdam' letters which previously stood in front of the Dutch capital's world- famous Rijksmuseum - as 'I amazonia'. The 22m x 3 m high replica sign aims to draw attention to another landmark vital to our survival which is disappearing in front of our eyes: the Amazon rainforest. Agency: Duval Guillaume
