PostCrossing and postcards

I collect postcards and love receiving them in the mail (I love receiving "real mail" no matter what it is since it is not a bill or ad).  Several years ago I learned about PostCrossing (“send a postcard and receive a postcard back from a random person somewhere in the world!”) which has helped my collection grow.  I also enjoy seeing the postage stamps from around the world and the airmail stickers in various languages.  This is the postcard I received this week from Germany.
