The series is part of the “Europa” series of postal issues. PostEurop, the association of European public postal operators, annually launches a theme for joint issues among member countries. To mark the 70th anniversary of the Europa stamp in 2026, it has chosen a unique theme aimed to “celebrate Europe’s rich cultural heritage, creating timeless symbols of shared values and aspirations.” It was selected through a competition won by Finland. “In today's turbulent world,” notes winner Klaus Welp, “there is an increasing need for peace, unity, and a strong community spirit, as well as reliable communication systems. A well-functioning national postal service is a fundamental pillar for democracies, providing security and connectivity for citizens.” In the design, the diagonal dotted line represents both the perforation of a stamp and the progressive work of PostEurop. The seven dots, connected by a straight line, symbolize the seventy years of joint efforts by postal operators across the continent. The shades and dotted patterns in the background form a cohesive and vibrant surface, reflecting the mix of colors in the European flag and symbolizing the unity of all the member nations.
