Optimistic letter Lou Gehrig sent to doctor up for auction

Yankees icon Lou Gehrig struggled to perform simple tasks — like buttoning his shirt — only months after retirement, but was still convinced he’d beat ALS, according to a heartbreaking letter penned by the Iron Horse.
A Southern California auctioneer is hawking one of the final documents Gehrig ever signed, a Sept. 13, 1939, note to his Mayo Clinic physician, Dr. Paul O’Leary.
