Paul Postma’s animation Er zijn meer dan 11 triljoen dingen te leren is based on the Children’s Stamps ‘Laat kinderen leven’ by Christian Borstlap. Borstlap had approached him because he thought it was possible to do more with his illustrations than just use them for the Children’s Stamps. The production of the animation flowed naturally from the illustrations. Christian’s illustrations indicated the direction the animation would take.

In the animation “Er zijn meer dan 11 triljoen dingen te leren” the simple figures on the Children’s
Poststamps designed by Christian Borstlap are brought to life in a catching way. Accompanied by the
song “Brother John” by Clutchy Hopkins & Lord Kenjamin, the theme of the Children’s Stamps, ‘Let
children learn’ is depicted in a clear manner.
