This folder contains correspondence relating to the commercial development of Edison's phonograph in Mexico. Included are documents concerning the formation of an Edison phonograph company in Mexico and the presentation of a phonograph to the Mexican president, Porfirio Diaz. Among the correspondents are Thomas B. Connery, Edison's phonograph agent in Mexico; Edwin M. Fox, a New York lawyer; and Juan B. Ceballos, a New York merchant. Fox and Ceballos were organizers and investors in Edison's Mexican phonograph company.

All of the documents have been selected except for coded cablegram messages and duplicate copies of selected documents. The cablegrams were originally exchanged in coded form among Edison, Tate, and Samuel Insull. The messages were subsequently decoded and transcribed by Edison's staff. Photocopies of decoded transcriptions relating to the phonograph in Mexico can be found in this folder. The original decoded transcriptions can be found in D-89-20 (Edison, T.A. - Secretary - Tate, Alfred O.).
