Vintage ink signature and inscription, “Best wishes, Ken, Lou Gehrig,” on the reverse of a 5.5 x 3.5 deckle-edge postcard of the Suwannee Hotel in St. Petersburg, Florida, postmarked in Fort Worth, Texas, on April 5, 1938. Gehrig has added the recipient’s address adjacent to the signature, “Ken Ruble, Bertram, Texas.” In fine condition. Encapsulated and graded by PSA/DNA as "MINT 9." A superb signature of baseball’s ‘Iron Horse,’ which boasts an uncommonly high encapsulation grading; Gehrig signatures rated “MINT 9” or higher are rare and highly coveted, with this representing one of the more attractive examples that we have seen.
