Four items signed by presidents, including: Woodrow Wilson (TLS as president of Princeton, declining an invitation to speak), Jimmy Carter (TLS on a "60 Minutes" appearance), George Bush (TLS regarding a "new venture"), and Bill Clinton (limited edition cover, numbered 61/150). In overall very good to fine condition, with varying degrees of toning and fading affecting all four item, with the text of Wilson's letter almost completely faded. The Bush letter is accompanied by the original mailing envelope.
