HI!I'm from Hong Kong!
You can send me a art or handmade postcard!
I do love something about mystery, especially mermaid and i would love to collect the illustrator postcard.
Glad to hear about the culture of your country. You can write in your country language but after is better to have a translation for me.
Since I like collect coins of different countries.It be better if you send coins of your country.
Just my suggestion in case you don't have any idea. :-)
In the postcard, please tell about yourself or the country you live.
