You've got mail ... and it's a postcard

Paulo Magalhaes loves to open his mailbox and find a brightly colored image of Rome's Colosseum. Or Africa's Victoria Falls. Or Peking's duck.

In short, he loves postcards, and the excitement of getting a scribbled note from someone far away.

"I often send postcards to family and friends," he says, "but you can imagine that after a while, you never receive as much as you send, and you realize that not everyone is into it. And that's totally fine."
