This folder contains correspondence and other documents concerning the repairs and registration of Edison's personal vehicles. Also included are items pertaining to technical development of automobile ignition systems. A few items bear marginalia by Edison. Among the correspondents are industrialist Henry Ford and his secretary Ernest G. Liebold. There are also letters and reports by employees of the Edison Storage Battery Co., including chief engineer Donald M. Bliss and sales manager William G. Bee.

Approximately 50 percent of the documents have been selected. The unselected material includes sales solicitations, invitations to events sponsored by the automobile industry that Edison did not attend, duplicates, and documents that duplicate the information in selected items.
