In 2018, the globally recognized photographer Ann Johansson set out to dramatize the effects of climate change. The campaign sought to connect cause and effect, problems and solutions. We designed the mailing in the form of a puzzle. Recipients were sent a poster with blank spaces, along with postcards that fit into the gaps. Once the elements were assembled, the main drivers and consequences of global warming became clear. A prize was offered to those who correctly completed the “puzzle.”
