American activist and author (1880–1968), who, through her tireless efforts on behalf of the disabled, and the fictionalization of her early education in the classic play and film The Miracle Worker, became the most famous blind person in the world. Vintage matte-finish 8 x 10 photo slightly trimmed in size to 7.5 x 10, depicting Keller examining a carved relief plaque, signed in pencil “Cordially yours, Helen Keller, March 16, 1938.” Trimming as noted, light corner creases (touching one letter of inscription), a hint of subtle silvering, and slightly indistinct contrast of writing against background, otherwise fine condition.
