The German Post has issued a new set of stamps having a "plus" and adding a few cents to the stamp price.
This feature exists for almost 50 years and is published in aid of German Youth Stamp Foundation. This Organization supports a number of measures for the benefit of children and adolescents.
The motives of this year's "youth stamps" let us look into the universe. The stamps depict the Horsehead Nebula, the Solar System and the Pleiades star cluster.
