On 28 June 2016 POST Philately invited the winners of the philatelic drawing competition "Biodiversity" on a price ceremony. Among the 1,700 participants, a jury had chosen ten winners from the primary, and ten winners of the secondary school classes and by a lucky draw among the contributing classes the 2E of the Lycée Michel Rodange. Carole Dieschbourg, Minister of Environment and Gaston Bohnenberger, Director of POST-Technology, handed the prizes over to the winners. The best two of the competition, Yann Klees (12) and Christine Guirsch (17 years) received each one a check of 1,000 euros and their designs will be printed as stamps bearing the artists name. The value will be 0, 70 € and 0.95 €. These stamps will be on sale from 13 September on.
