On May 6, Itella Posti Oy issued 15 different stamps on the themes of the world heritage site Struve Geodetic Arc, Finnish forests, everyone's long-time favorite Moomins, and the Happiness Tree, suitable for different greetings in the spring and summer.
The Struve Geodetic Arc was used for determining the size and shape of the globe. The arc, which is approximately 2,820 kilometers long, extends from the Black Sea in Ukraine all the way to the Arctic Ocean in Norway. The arc was named after F.G.W. Struve who managed the measurement in 1816-1855. The arc measurement stations are located in ten countries. The 34 most representative measurement points were included in the UNESCO World Heritage List as a joint site of ten countries in 2005. The miniature sheet indicates the six points located in Finland. The two stamps in the release are within each other in the miniature sheet. The outer stamp is round, and the inner has the shape of the map of Finland.
New technology in forest stamps
Forests is the theme of the joint Europa stamps of European postal administrations and companies (PostEurop) this year. According to the theme, graphic designer Klaus Welp has designed two stamps for Finland presenting the four seasons. The text in the stamps is placed so that they can be used according to the seasons. The views on the stamps are from Lake Mustalampi in Nuuksio National Park.
The forest stamps have been implemented with new finishing technology where an actual perforation has been made on a stamp of self-adhesive material. In addition, the background paper has a tear-off zone, facilitating the removal of the paper. The new technology enables the combination of a traditional stamp look and the usability of a self-adhesive stamp.
