My entry for today is one of the several “unusual-shaped stamps” by the Finnish Post Office this year.
The Finnish PO never fails to surprise us with their unique issues every year! The stamp is a glow-in-the-dark kind :D
Lovely dahlia flowers on Finnish stamps – above is one of the pair of self-adhesive, second class stamps that the Finnish PO circulated in April.Dahlias originate in North America and Mexico and they were brought to Europe as early as in 16th century. The two incandescent dahlias are easy to pick up from the dark sheet reminding old time wallpaper.
On the sheet there are ten self-adhesive stamps, it makes five pairs. - Source
