This nice cover from Zambia was sent by Déo, thank you! It was posted in Lusaka on June 4 and arrived on June 19, 2015.
The stamp depicts the Victoria Falls and commemorates the 50th anniversary of independence in 1964.

I am Florian, a 36-year-old cover collector from Austria. I am trying to receive at least one cover from every country of the world. If your country is on the list of missing countries, please send me a cover, I am replying with a nice-stamped one from Austria!
