Steiner Sports has listed a diary used by Joe DiMaggio's from 1981 through 1993 with a starting bid of $1.5 million. From the AP:

The diaries reflect the demands on the Yankee Clipper and some of the pressures of his 56-game hitting streak.

"If I thought this would be taking place," Joe DiMaggio laments in a diary entry about the public relations frenzy, "I would have stopped the hitting streak at 40." ...

How does [Whitey] Ford think DiMaggio would feel about his diaries being made public? "I don't think he would be too tickled about it."
