San Francisco native Ossie Vitt got his start in the Pacific Coast League, moving to the Bigs in 1912 and building a ten-year career with Detroit and Boston.  Vitt had a reputation for being difficult to strike out, and remains one of the toughest all-time, with a lifetime strikeout every 26.6 at bats.  Vitt passed away in 1963, his signature on cards remains extremely difficult as a result.  This example does have scrapbook residue on the reverse.  The card originates from the Shibe Park collection of autographed cards, an original owner collection carefully collected by a teenage boy who, in 1939 and 1940, obtained many autographs from players arriving at the train station near Shibe Park, and continued for many years to obtain signatures in person and through the mail.
