RARE Arizona Thunder soccer ball, signed by nearly the entire 2000 World Indoor Soccer League (WISL) team. This was the Thunder’s final season, making this a unique and highly collectible piece of Arizona sports history. The ball features numerous player autographs, Signatures are clear and legible, and the ball has been well preserved. The Arizona Thunder only existed from 1998–2000, so signed memorabilia from the team is extremely scarce. This ball is an excellent collectible for soccer fans, Arizona sports enthusiasts, or indoor soccer history collectors.
