The last week I was in Austria and during that time arrived not only eleven postcards but also two covers including one from Russia.
Russian Kremlins (from set of twelve) (issued 01-10-2009)
Medals (from set of four) (issued 05-05-2015)
Inside were a mint version and a FDC of the new Russian Postcrossing stamp (issued 25-03-2016).
Thank You very much Anastasia!
