This is some type of team award from the 1987 Minnesota Twins, World Series winners. This appears to be made of some type of crystal glass and is rested on a wooden base with the plaque. It measures roughly 3 1/4" tall and the ball is about 2 1/2" in diameter. This is a unique and rare find for the hard-core Twins Collector. Please see the photos very closely and if you have any questions please ask.
