Moomins & first day cover

I decided to start with this set because it is really especial for me. It was sent by my good Finnish friend Heidi, from the meeting of Postcrossing that they had in Jyväskylä, Finland. In the picture you can see the envelope were the things came in and then, the interesting stuff: The blue envelope is the First Day Cover, it was issued with the postcards and the stamps in May 2013. You can see that the stamp/cancellation is special too. Illustration was made by the awesome Tove Jansson (as we know, the creator of the Moomins), and the design of the FDC and the postcard was made by Satu Lusa.
