The Adidas Tricolore was the 1998 world cup ball and was one of the most popular world cup balls of all time. It was the first world cup ball with more than two colors, hence the name.
The Adidas Al Rhila was the most recent world cup ball and is already a classic. Being used in what some would say is the best world cup final of all time.
The Adidas Telstar is the most iconic ball of all time. It is what set the black and white soccer ball precedent that is still common today. If you ask someone to draw a soccer ball, they will draw a Telstar whether they know it or not.
The Adidas Fevernova broke many precedents when it was released in 2002. It was colorful and full of design. Things that had not been done before in a world cup ball.
