This card came to me from Finland, from a fairly young postcrosser. She wrote about the card on the back and also gave me a little info about the stamp. Hurray for her!
She wrote, "Hello! My name is Iiris, and I am a 14-year-old girl from Finland in a town called Kotka. I hope you like the card.
The bear says:
I just got your letter!!
The man on the stamp is Jean Sibelius, the most famous composer in Finland. (He's dead..)
