This appears to be a custom-made card! There is a Postcrossing message on the front, and the same icon on the back with space for the ID. I'm not sure if she created it herself. The picture is cute, in any case.
On the back:
Hello Jennifer! Greetings from Belarus! Recently I read a quote and I liked it very much: "The one who is out of step, hears another drum." (It's from Ken Kesey Over the Cuckoo's Nest). Yesterday we had the first snow. I like snow. Have a good day!She drew stars around "I like snow" so I guess she really likes it! It's been a really long time since I've read One Flew Over the Cuckoo's Nest, maybe it's time for a re-read. The stamp is an abstract flower design.
