Walter Johnson's family is putting some keepsakes up for auction.
A ticket from Game 7 of the 1924 World Series is one of the items up for bids Saturday at Heritage Auctions in New York. It's thought to be the only surviving ticket from the game that still has its perforations intact, having never been torn by a ticket-taker.
Johnson's daughter, Carolyn Thomas, just turned 90. She and her son said it was simply time to start parting with some of the memorabilia and pass it on to the next generation of collectors.
Other items for sale include the personalized framed copy of Johnson's plaque from his Hall of Fame induction and a handwritten congratulatory letter from Ty Cobb.
