Winegrad, Dilys Pegler, ed., The Intellectual World of Benjamin Franklin: An American Encyclopaedist, at the University of Pennsylvania, an exhibition catalogue (Philadelphia: Smith-Edwards-Dunlap, 1990).

The Rare Book & Manuscript Library maintains a copy of the Declaration by the Marquis de Lafayette (June 26, 1906) (a descendant of the Marquis de Lafayette who served as Washington's aide de camp) in which he avows the walking stick's authenticity, stating: "Rush walking stick with ebony handle given to the General Lafayette by Benjamin Franklin. The stick was constantly carried by Franklin. In the middle is a silver plate with the initials 'B.F.'" An additional document, a statutory declaration regarding the Lafayette Relics of William Sanders Fiske (the solicitor of the above Lafayette), notes that the walking stick is the one that was owned by Lafayette.
