The oldest surviving tennis ball is over 160 years old - Apparently.
In 1853, a tennis ball was used in a match at the All England Lawn Tennis and Croquet Club in London. This ball, made from pressurized air-filled rubber, is now on display at the club. The ball is a significant artifact, as it predates the introduction of felt-covered balls, which are the standard today. The club's archives confirm the ball's age, and it is considered a rare and valuable piece of sports history.
