Here is a stickered card from a postcrosser in Cologne. I love the postal cancellation stampings she made on the front. In the back, she had a group of postcrossers sign the card. She attended an all-day Postcrossing meeting, where she met aficionados as well as the founder of Postcrossing, Paulo Magalhães and Ana Campos (designed the Logo). They all went shopping for cards, then wrote and signed a pile of cards, while exchanging stories about their postcrossing adventures. Sounds like fun!
