TNT (now PostNL) commissioned us to design 10 postage stamps for its standard catalogue. The theme was the environment. The stamps can be seen as 10 cheerful encouragements and practical tips for a greener lifestyle. With the slogan ‘Think Green Act Green’ (‘Denk Groen Doe Groen’), the stamps also became a stamp-sized campaign. Awarded with a ‘Best of the Best’ Red Dot Award in 2008.
