Notorious criminal (1890–1963) who, while imprisoned, became a self-educated authority on birds and earned the nickname 'The Birdman of Alcatraz.' ALS signed “Love, Bob, Robert Stroud, 594,” one page, 8.5 x 10, October 25, 1948. Handwritten letter "From Robert Stroud, P.M.B. 594, Alcatraz, California," to his sister Mamie, in part: "I have your letter of the 18th and am sure glad to hear from you, but you do not mention your health directly, so I presume you are still having trouble with your heart. I wrote to Marcus about that and I told him that you had not been to a doctor, probably because of the expense. Well, I told him to send you enough money so you could have the heart checked…I have been working hard the last few days on some papers which have to go to the court tomorrow. I don’t know whether or not Marc told you of my suit…I have a perfect case…I am feeling fine and have finally gained about two pounds. I weighed one 46 this morning with only pajamas on…I was dehydrated when I came to the hospital…I have nice, comfortable quarters, a good bed and a chair. The first time I've had a chair in over five years. Sitting on the floor is hard on the bones at my age. I also have a surgical bed, and by raising the end of it can use it for a very convenient desk. Another virtue from my point of view is that I have the room to myself and can close the door when I wish and read or write all night long." In fine condition. Encapsulated and graded by PSA/DNA as “MINT 9.”
