Thanks to Davor, from Zagreb, I received this beautiful cover, the first one from Croatia. On the right corner up we can see a stamp with Pope John Paul II, one among my favorite topics.
I invite you to have a look at the interesting Davor's web-site: www.geocities.com/davor2405/philately.html
He collects stamps ww related to aviation. Certainly you have something he is looking for, and vice-versa.
Thank you again, Davor, for your nice cover, your stamps and the post cards, as well.
