[ Autographs ] Nathan Leopold 1904-1971 American criminal who, with Richard Loeb, was convicted in the thrill-killing of a 14 year old. Saved from the chair by Clarence Darrow's brilliant defense. T.L.S. 1p. 4to., Puerto Rico, Oct. 15, 1960 to a fellow bird-watcher. Leopold describes his bird-watching exploits, mentioning that he has seen 101 species in one day and hoping he will have an opportunity toco-author a bird book. With two candid photographs, presumably of Leopold. Very good.
