2021Christmas - First Day Cover

At first glance, this year’s special stamps seem to depict a wintry graphic pattern. However, a closer look quickly reveals that the two snowflakes have incredible symmetry. Hypersymmetrics, or “multidimensional symmetry” is a form of artistic representation developed by Jens W. Beyrich. Twelve stars, which make up the basic form of the snowflakes, can be configured in 1016 different ways. If each one was drawn on a beer mat, they would cover the surface of the earth.
