Two blank postcards sent in an envelope by Elena :) The first one shows the map of Ukraine and the second one shows the Kharkiv Passenger Railway Station.
It shows the map of Kraków. You can see the Stare Miasto and Nowa Huta, which I've visited by the way. Also the famous Wawel dragon :D This postcard was sent by Justyna on 17th March and arrived on the 30th :) Took only 13 days!
