Vintage 5×7 matte finish sepia tone chest-up publicity portrait, boldly signed in black fountain pen, “Good luck/Betsy Blair.”  Fine condition, with mild creasing to the top right corner tip.  Betsy Blair appeared in such films as Another Part of the Forest and The Snake Pit before her burgeoning career ground to a halt because of the Hollywood blacklist.  She was finally cast as the female lead in Marty (1955), at the insistence of then-husband Gene Kelly, who threatened to stop working at MGM if she did not get the part.  Marty proved to be her career peak, garnering her an Oscar nomination.
