On 9th March I got five postcards: two from Finland and three from South Korea.
One of the cards from Finland shows characters from the video game Angry Bids. Angry Bids is a video game franchise developed by the Finnish company Rovio Entertainment. It was first released in 2009 and since then many different versions for different systems has been released. The Angry Bids games belong to the best-selling video games of all time.
With a matching stamp:
Angry Birds (from set of six) (issued 09-09-2013)
Thank You very much Sini!
