Every year since 1924, the Dutch Postal Service has worked together with the Stichting Kinderpostzegels Nederland (SKN), or the Foundation for Children’s Welfare Stamps Netherland, to produce a series of stamps to help disadvantaged children both in and outside the Netherlands. The last campaign raised more than 9.3m euros to fund educational programs. The special edition stamps, which cost a little more than regular stamps, have been sold door-to-door by Dutch school children since 1948. Art director Christian Borstlap from Kessels Kramer Creative Collective designed this year’s playful worm-like creatures, which were featured both on the stamp series and on postcards. The little worm people were turned into an animated commercial by Paul Postma Motion Design.
