Charles Kingsford Smith (1897-1935, Australia's most famous early aviator), signature on 28th May 1935 letter on 'Sir Charles Kingsford Smith' letterhead, thanking the writer for his kind letter of sympathy and congratulations (following his unsuccessful attempt to fl y the Jubilee airmail from Sydney to NZ, due to engine trouble halfway across the Tasman). Letter with some tone spots, though excellent signature.
