San Francisco newspaper from July 18, 1941. Not sure if you can see it in the compressed photo, but in the top left corner, Joe DiMaggio "blames" Ken Keltner for stopping some nice hit streak he had going.
Thanks to Ben for pointing this auction out to me.
I also got the paper from the day before, where ironically, all they seem to care about is Joe facing Bob Feller the day after, and whether Bob can stop the streak.
