These special items were put away over 40 years ago by Lennart Bergelin. The shoes have clay stuck in the grooves which would seem to show that they were used during the French Open at Roland Garros. Bjorn Borg was known to use his gear till they had nothing left to give and these items show that type of wear. The shoes are Diadora and they sponsored Borg for most of his career.
The head band is a nice style match to the photo of Borg, as are the shoes. Very hard to find anything like this from the first Rock Star of Tennis.
