I love to receive old-fashioned letters or postcards. And also I love sending them. However, in some countries it's particularly difficult to find postcards (sometimes I found them after traveling for 3 weeks) or, even worse to find post stamps. Sometimes I had both and I couldn't find a post box for days! It's a big hassle so now I am sending my friends and family postcards with my own pictures.
If you collect postcards from different countries like I do, you get now the opportunity to receive a personal one.
