Yashin-n,you can be very happy - You've got a signed tile by Doris Matthäus herself - there are only a few tiles in the world which she signed.
I had around 15-20 mini expansions (German Monasteries, De Kloosters and Castles in Germany - signed by Doris Matthäus - The Castles of Germany have also the sign from Klaus-Jürgen Wrede) - the mini-expansions are now worldwide at their new owners. I think Doris Matthäus signed in total worldwide around 30-50 tiles. I will ask Udo Schmitz (Carcassonne-on-Tour).
As kettlefish spotted, that's a Doris Matthäus tile! You're incredibly lucky!
put it in two clear bags and a box!
You can play with the signed tile and have fun to look at it during the game play. The owner of the signed monastery gets some extra points.Or you can put the tile into a frame and put it onto a wall.
