We recently had a mailart 365 reunion at our house with andytgeezer, Elena, stripygoose and positively postal. At the end of the night, positively postal left a rubber stamp at our house. Luckily, he also left the enemies that it was originally sent to him in, complete with address and unused stamp. Hurray for those times when the postman doesn't cancel the postage.
A quick Usagi later and it was back in the post
