The two anniversary stamps are dedicated to Pro Patria’s 1 August badge: 100 × Switzerland, 100 × diversity and solidarity. In chronological order, the stamps portray all badges since 1923 and present a century of social and cultural change on a tiny space. The 1 August badge symbolizes the Swiss people’s willingness to help others better than anything else. Swiss Post branches and volunteers – individuals, schools and associations – have been selling the badge for almost 100 years. In the past, the proceeds mainly went towards social projects, education, the advancement of women in society and many other initiatives. Today, Pro Patria focuses on Switzerland’s unique cultural treasures.

The heraldic silver and Swiss red enrich this year’s stamps to produce a historic document featuring all of the previous 99 badges. In 100th place, the Swiss Cross can be seen. This can be interpreted as a plus sign, leaving space for new additions and the future – but also for the yet-to-be-revealed 100th badge.
