This folder contains correspondence relating to industrial exhibitions in which Edison participated or was invited to participate but declined. Included are letters concerning the display of Edison products in New York at the Second National Exposition of Chemical Industries and at the American Association for the Advancement of Science, as well as a request for models of Edison's early inventions and a question about Edison's use of a special telephone at the 1915 Panama-Pacific International Exposition in San Francisco. The correspondents include Claude E. Holgate of Newark's Anniversary Industrial Exposition, mineralogist George F. Kunz, and chemist Charles F. Roth.

Approximately 20 percent of the documents have been selected. Most of the unselected items are invitations, congratulatory notices, or other formal communications to which Edison did not reply. Also unselected is routine business correspondence relating to the various exhibitions, most of which was handled by William H. Meadowcroft.
