In some parts of the world, it is a real challenge to find postcards, so I decided to create a list, hoping it will be helpful to fellow travelers who like to send or collect postcards from the places they visit:

Please help me add new cities to the list! If you know of any shops that sell postcards in cities where postcards are hard to find, send me a private message. Thank you!
