Yesterday I got six postcards: one from Russia, four from Germany and one from Singapore.
The card from Russia shows the tomb of Immanuel Kant at the Königsberg Cathedral in the Kaliningrad Oblast. Immanuel Kant was born in Kaliningrad and also died there.
With a nice stamp:
Sergiev Posad (issued 24-06-2014)
50 years First Spacewalk (issued 10-04-2015)
Thank You very much Anastasia!
