Vintage 1920s 3.5 x 5.5 matte finish black and white chest-up publicity portrait from the “Ross” studio boldly signed to the bottom border in blue fountain pen.  Very fine condition.  The well-established German film star relocated to the United States following the rise of the Nazis, appearing in such Hollywood films as Come and Get It (1936), Heidi (1937), and Letter From an Unknown Woman (1948).  Uncommon this early.
