A natural spectacle in four acts: the stamp set highlights how the seasons are experienced in Switzerland in a colourful, eye-catching way. The designs harmoniously and dynamically combine elements from nature, animals and human activities: in wintertime, the focus is on fresh snow, fun on the slopes and fondue. In spring, crocuses bring colour back to our gardens, while you can’t miss a refreshing dip in the cool water or a delicious ice cream in summer. When the hot and sunny days start to fade, the leaves turn brown and a cool wind begins to blow, migratory birds set off for their winter destinations and forest animals like squirrels start preparing for the coming cold season.
