In 1971, the horticulturist Werner Fischer from the German town of Vilsbiburg, developed a revolutionary stringing pattern. The pattern supported an extreme topspin to the ball. The local tennis team from Vilsbiburg made the march from the lower district leagues to the Bundesliga with it. In 1977, the tennis world would face a historical showdown. Argentine world number 1 Guillermo Vilas played against Rumanian Ilie Nastase in the final of the ATP in Aix-en-Provence, France. Surprising the spectators and shocking Vilas, Nastase entered the arena with a Spaghetti-strung Adidas ads660. Vilas, managed by former Boris Becker manager Ion Tiriac by that time, lost the match after 53 consequetive victories in a row. Following a harsh protest from Tiriac, the ITF eventually banned the Spaghetti strings from the scene.
The Berlin Tennis Gallery received the below exhibit from Werner Fischer. It is one of the original rackets used by Nastase in the 1977 battle of Aix-en-Provence.
