The product is a custom Detroit Tigers jersey signed by former baseball player Denny McClain. The inscription on the jersey reads "31-6, 1968," which likely refers to McClain's impressive win-loss record in the 1968 season...the last time a pitcher had at least 30 wins in a season. This collectible item would be a valuable piece for fans of the Detroit Tigers or baseball enthusiasts looking to add a unique and personalized item to their collection.
