Actually this FDC was issued in 1994 to celebrate the 150th anniversary of Croatian tourism, and is one of 3 FDCs as there were 7 stamps in a set. This one shows the national parks in my region: Plitvice Lakes (UNESCO), Kornati Islands (my workplace!) and Krka waterfalls.
I have posted an entry on Sunday Stamps' landscapes theme on my postcard blog before remembering that I have this FDC, I hope noone will mind me having two entries xD
