Thomas Muster is auctioning off his Paris trophy for a good cause.

When Thomas Muster won the 1995 French Open with a three-set win over American Michael Chang, the local legend wrote a big piece of Austrian sporting history. After all, Styria was the first red, white and red tennis player to win a Grand Slam trophy. It also has a resounding name in Paris: the “Coup des Mousquetaires.”

And that trophy, among other things, could be in your gallery in the near future. So Muster decided to give away that trophy, along with his world number one trophies and all eight of his Masters titles. Not to pay off any financial debts, but for a good cause.

They will be dusty.

The unusual memorabilia will be auctioned off, with the proceeds going to Ö3 Christmas Miracle and benefiting the “Licht ins Dunkel” foundation for emergency aid and families in need. The pattern: “At home they will end up gathering dust somewhere. We hope that with the donation amount we can provide significant help to those who have not had it so well.

The auction, which will be held on the Aurina auction platform, starts on October 8 and runs until November 3.
