Glossy 8×10 black and white bust studio portrait, boldly signed and inscribed in black felt tip ink, “To Mike/Best/Sondra Locke.”  Very fine condition.  The actress is best remembered for her six-film collaboration with Clint Eastwood, which ended in acrimony following the failure of her directorial debut, Ratboy (1986), a critical and box office flop that effectively spelled the end of her career.
