These are my first two cards I've sent out in the "Postcrossing", where people more or less randomly send cards to other people, world-wide. The card above is a multi-view continental sized card that I bought a while back in a local drug store. It's going to a person in Austria who likes cards of the area in which the sender (me) lives. These are scenes around Valdese, NC, so it fits the bill. The card to the right is a 50 year old standard/chrome of Rock City on Lookout Mountain near Chattanooga, Tennessee, and it is off to Findland. I'm not sure if the person will like it or not, but she said she liked landscapes, mountains, geographic features, so maybe this counts.
The way I understand it to work (we shall see), is you have to register at www.postcrossing.com then request and address. An address is displayed along with a registration number. You write the registration number on the card, and send it to the address. When the person receives it, they log on & enter the registration number. At that point you're put on the list to receive a card, and when your name comes up, someone sends you a card. We'll see how it works. I've always liked postcards, it appears to my visual nature. It was a long time before I ever read an article in National Geogrpahic - I'd get too involved in the pictures.
I found out about this on another blog - A Postcard A Day, which posts a postcard every day. Its an interesting site - check it out at www.apostcardaday.blogspot.com.
