Aren't they beautiful? I love both frogs and trains and I will treasure these cards. I thought both of them came from Postcrossing forum tag game, because the one who tagged me said she has both frog and train card, but sctually that cute froggy came from my Finnish pen pal. I was so surprised! She wrote such lovely words :'( Thank you! Both of them will have a good spot among other cards :)
Here are Finnish and Ukraine stamps.
