The theme of the 2020 Nordic stamp series is mammals, and the Åland stamp illustrates the mythical bat silhouetted against the bell tower of the Mariehamn City Library. 10 different species of bats have been observed in Åland, the Northern bat (Eptesicus nilsonii) being the most common. Fluorescent printing has been applied to parts of the motif which glows in the dark. To observe the luminescence, you must first ”charge” the stamp with light before you enter a dark room. The more you “charge” the luminous print with light, the stronger the effect.
