Hideo sent me this nice letter from Japan, thank you! It was posted in Mie prefecture on April 8 and arrived on April 10, 2012.
The mini-sheet was issued on November 11, 2011, and commemorates the Chinese Year of the Dragon.
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!
