First-day cover «Natural patterns»

Nature is full of intricate structures that are often hidden away: delicate veins in leaves, gills under mushroom caps or patterns of ice and wood. The new “Vine leaf” and “Mushrooms” stamps bring these details to life on the stamp in miniature format. They show how small shapes and lines create whole arrangements and raise awareness of the beauty in detail. The stamps are setting new technological priorities: for the first time in Switzerland, a data matrix code has been integrated that makes sorting easier and increases security against forgery, without restricting design freedom. The stamps combine nature observation, creativity and modern technology in a small collector’s item.
