20-time Grand Slam champion Roger Federer wore this Nike bandana during the 2006 Australian Open, which he won. The 2006 Australian Open was Federer’s 7th overall Grand Slam win, and second Australian Open title. The 2006 season is considered Federer’s best, and perhaps the best ever for anyone; it was this season in which he won 12 titles, including 3 Grand Slams, the Tour Finals, and posted a 92-5 (94.94%) overall record. This match worn bandana from the tournament was also autographed by Federer, and it includes a Certificate of Authenticity from the Federer Foundation.
