Jimmy Doolittle’s autographed “good luck” silk scarf, which he wore at the 1932 Cleveland Air Race and during the Doolittle Raid.  A letter of provenance from Doolittle and a signed commemorative print of the raid signed by 24 of the Raiders are also in the case.  On display at the Sgt. Richard Penry Medal of Honor Memorial Military Museum in Petaluma, California.
