I found this most excellent website by watching the English version of Euromaxx on DW TV. I think this is awesome. I always send postcards home when I am on vacation, even if I am just going a few cities away. My father is the most common receipant of these cards.
I am a Mom of two little boys and they love to receive mail that is not asking for Mama's money (bills!). I would prefer cards with pictures of things unique to your country, especially churches and castles. I am also a very passionate reader and would love anything related to books or coffee. Please no ads and try to avoid cartoons and children's card, as the cards are for my collection and not my children.
I love the mail and hope to send many more cards in the future from my beautiful land of Canada!
