Every card here gets mailed to strangers, over and over, as long as it is in rotation. $19 takes one out of rotation permanently. It is never mailed again by anyone, its page becomes the record, and the record says you are the one who did it.
One owner per card. There is no second copy and no way to un-retire one. If you would rather just mail one to somebody, that is the mailroom and it is cheaper.
Empty. Nobody has retired a card yet. The first one on this wall stays first forever.
