Youthful 8×10 glossy black and white head and shoulders studio portrait, boldly signed in later years in fine-point black felt tip ink.  Very fine condition.  The adopted son of Helen Hayes and playwright Charles MacArthur enjoyed a four-decade career that encompassed a wide variety of roles, but is best remembered for his starring role as Danny Williams, a part he played in 259 episodes of the long-running television series, “Hawaii Five-O.”
