I found out about this from my geocaching experience. I love to visit different places, and this looks like a great way to learn about the world.
I am happy to receive any style of card. As I am an artist I can appreciate many styles of cards. As I am a history buff, vintage cards from your hometown would interest me. Cards with maps would be very cool too. As a last thought, basically any type of card would be great so surprise me!
In return I would be happy to try and fulfill the style of card you would like to receive.
I will also send a return card if you provide me with your address, either on the card its self, or by U2U.
I would prefer that the cards be mailed themselves, not in an envelope.
I hope that my effort helps will bring all of us in the world just a little closer.
