A 1911 "Shoeless" Joe Jackson autographed photograph by Frank W. Smith sold for $1.47 million, the most ever paid for a signed sports photograph.
The photo was offered by Christie's and Hunt Auctions in New York.
According to Christie's, it is the only known Jackson-signed photo of himself in existence.
Jackson was notably illiterate and avoided signing documents if he could. His wife signed for him mostly after his playing days ended.
