TLS signed “Many thanks, Jack,” one page, 6.25 x 8, United States Senate letterhead, May 23, 1957. Letter to Andrew R. Quigley, in part: "It was very good of you to send congratulations upon the award of the Pulitzer Prize to 'Profiles in Courage.' Needless to say, I was most gratified by the announcement; and the pleasure of it all was heightened by the generous messages I received from you and other friends. Thanks for thinking of me—but don't count on a repeat performance!" In fine condition, with creasing to the lower left corner.
