Postcard from Russia

The sender gave me a postcard in return of the postcard that I sent to her in Postcrossing.
I was puzzled but amazed when I discovered that this is a some kind of  Holographic postcard where it will come alive when you watch in your smartphone. A certain app must be downloaded to see it.
Its my first time to received such kind of postcard. Thank you very much sender! I love the concept of this postcard. I received this card last July 26, 2018.
