A game-worn Johnny Unitas jersey from the 1967 season is a last-minute addition to a Super Bowl week auction in Phoenix, Ariz., and is expected to sell for anywhere between $50,000 and $100,000.
The auctioneer, Hunt Auctions, said the jersey was given to the consigner's family by then-Colts equipment manager Fred Schubach in the Memorial Stadium locker room in 1968.
The jersey was framed and hung in the consigner's family home, and a photograph of it was featured in a 1978 issue of Sun Magazine.
Unitas, the longtime Baltimore Colts star, earned national renown for his role in the 1958 NFL Championship game, the precursor to the Super Bowl at which his game-worn jersey will be sold.
According to the listing, the jersey "rates as one of only a scant few documented Unitas game jerseys to have entered the marketplace. Museum quality and categorically one of the finest examples in private hands."
