Itella Posti Oy is making history by releasing the world's first official Angry Birds stamps, featuring six of the popular game characters - five birds and one pig. The designer of the stamps is Toni Kysenius, Art Director at Rovio Entertainment, who also designed the HockeyBird character and related stamp issue for last year's IIHF Ice Hockey World Championships.
In order to ensure authenticity, the Angry Birds stamps feature a pattern which is only visible under UV light. In addition, an irregular perforation follows the shape of the characters. The sheet of six 1st class stamps also includes Priority labels fitting the appearance of the stamps.
